1. No Resistance. Instead of rehashing the Rebels vs Empire conflict, I’d just have the Republic face the First Order directly.
2. Han is an admiral in the Republic fleet and Chewie, Lando and Wedge are generals.
3. Luke would be looking for the first Jedi temple, but not because his Jedi order failed. He would be searching for answers to defeat the First Order. He would remain in contact with Leia through Artoo until said communication is suddenly lost. Artoo would be kidnapped by the First Order to try and pry Luke’s location from him and the assault on Starkiller Base would be about rescuing him. (The reason Luke stays on Ahch-to, which would be Tython in my version, is because he finds some terrible secret about the Jedi and decides he has to stay to protect it.)
4. Luke entrusts Leia to his Jedi order in his absence. The new Jedi temple is on Takodana.
5. Kylo Ren and Ben Solo are separate people. Kylo Ren is still a former student of Luke’s, but he doesn’t single-handedly destroy all his work. He’s a Jedi killer who collects lightsabers like General Grievous. (He’s the reason the Jedi temple is no longer based on Coruscant.) Ben Solo’s main drive is to best him after Ren humiliates him.
6. Jakku is a desert swamp like in the original concept art. Just to differentiate it from Tatooine.
7. Rey’s parents actually are nobody and this is cleared up pretty quickly. Star Wars isn’t about speculative fan theory mystery boxes; the reveals come out of nowhere. No one walked out of ANH thinking, “I bet Vader is Luke’s father!” Nobody’s going to wonder who Rey’s parents are either.
8. Ben Solo replaces Poe in the trio (not that there was much of one) but Poe is still an ace pilot and gets around the same amount of screentime as he does in TFA. Poe gets a bigger role in Episode VIII (more on that later.)
9. Starkiller Base is an ancient Sith weapon that was non-functional when the First Order found it. Snoke has just recently discovered how to fix it.
10. The map to Luke is actually an ancient paper map to Tython. Make it really clear that this is not a map to Luke, he didn’t say “I’m going to go hide, nobody follow me but I’m going to leave a piece of my map with my droid” and just not have that confusing stuff. The map is just a really old map that Lor San Tekka found that might lead to Luke’s location, but might not because Luke didn’t have a map and may have ended up in the wrong place.
With these, my plot would go like this:
Leia learns that Lor San Tekka has the map to Tython and sends her son Ben to meet with Lor San Tekka. When he gets there the First Order arrives to take the map. Ben gives it to BB-8 and tells him to take it. Kylo Ren kills Lor San Tekka and Ben attacks him. Ren defeats Ben and takes his saber.
FN-2187 decides to defect, but needs a pilot, so be breaks Ben out. This plays out like his escape with Poe except Ben doesn’t disappear during the crash. Instead they head out together in the desert to find an outpost so they can leave the planet.
Rey finds BB-8 and runs into Ben and Finn. Ben sees she’s Force sensitive and wants to take her with them, but Finn just wants to get off Jakku and Rey doesn’t want to leave because she’s waiting for her family. The three of them are forced to flee in a junk ship (not the Falcon, because Han still has it) and once they’re safe, Ben contacts his father to pick them up.
On board the Falcon, Ben tells Han of Rey’s Force sensitivity and says she needs to be brought to Leia for training. Rey just wants to go home and Finn just wants to go anywhere the First Order isn’t, and they bond over their disgust of Ben’s stubbornness. But when Finn tells them about Starkiller Base, Rey realizes she can’t go back to Jakku because the First Order might destroy it and declares that they have to stop them, but Finn still wants to run, so they tearfully part.
Rey is brought to Takodana where she is given a lightsaber by Leia. (Ben gets a new one to replace the one Ren stole, though he really wants to get his old one back.)
The First Order captures Finn and Kylo Ren decides to hold him hostage when he finds Rey in Finn’s mind. The First Order contact the Republic and demand the Jedi hand over Rey or Starkiller Base will destroy Coruscant. Ren tells Leia Finn is Force sensitive (he thinks he’s lying, but he’s actually right.) Leia and Ben go to Starkiller Base with Rey employing a ruse while Han amasses the Republic fleet to attack Starkiller Base.
Finn escapes and tries to create a stormtrooper rebellion only for Phasma to stop him. Ben, Rey and Leia come to his rescue, sending Phasma on the run. Finn takes the stormtroopers he’s managed to convert on a mission to cripple Starkiller’s shields and weapon, while Ben goes off to confront Kylo Ren. Leia and Rey search for Artoo.
Rey and Leia find Artoo and Leia takes him to their ship while Rey goes in search of Finn, who has just managed to get the shields down. She finds Ben about to get his butt handed to him by Kylo Ren and distracts Ren by attacking him. The two of them fight together.
Finn realizes he needs the Force to shut down the shields and goes off to find Rey and Ben, who are Force sensitive (he doesn’t know that he is too.) He arrives just in time for Rey to receive the wound he receives in The Force Awakens. Finn picks up Rey’s saber and he and Ben fight Kylo Ren. Finn’s stormtrooper rebels come to the rescue with Leia and Finn hightails it with a wounded Ben and an unconscious Rey.
Ben and Leia shut down the firing mechanism while the Republic’s bombers damage it permanently, as well as taking out most of the station’s mobility. The protagonists all flee with several new stormtrooper defectors.
Finn tells Rey he loves her and Ben promises to pass on the message when she wakes up. Ben, Rey and Leia head off with Artoo to find Luke while Finn gets acquainted with Poe. Finn talks with Han and Poe about turning his stormtrooper band into an elite Republic squadron.
Episode VIII- Finn joins Black Squadron to learn some piloting skills while training his stormtrooper commandos. Finn and Rose would be Poe’s wingmen and they’d form a trio. Ben would struggle with feelings for Rey, knowing that Finn loves Rey and Rey loves Finn and ultimately choosing their happiness. Luke’s secret would be something dark, and to his shame, he would have used this secret, a shocking reveal made by Kylo Ren at the end of the film. However, I would make it something that would be within Luke’s character. Maybe it’s a forbidden dark side power or something. Luke would sacrifice himself, but his death would mean something this time and the battle would take place on Tython. Finn’s Force sensitivity would be revealed (after being hinted at to the audience in the previous film) and he and Rey would be united again to kick butt in IX. Rey would see Luke as a father figure and take on the Skywalker name.
Episode VIII would not be called The Last Jedi because that’s a stupid and uncreative title. Rian Johnson would not be involved in any way with VIII.
No idea what I’d do with IX but I know Rey, Finn, Ben, Poe and Rose would form the baddest gang in the galaxy and restore motherflippin peace to the galaxy. I’d probably have Finnrey Jedi babies to show that this is the VERY VERY end of the Skywalker saga. Luke’s ghost would play a major role in IX. JJ would not be in charge of this one because he’s bad at satisfyingly ending things but for consistency’s sake he will be consulted heavily (unlike with TLJ.)
Anyway that’s my ST. I couldn’t find a place for Maz Kanata which is a shame because I like the concept of a Force sensitive smuggler who runs a castle bar. Maybe I’d have that instead of Canto Bight. (Although the “on the run low on fuel” plot from TLJ is hot garbage and I wouldn’t have VIII do anything like it.)
Edit: I just clicked submit on my idea for Episode VII and totally
forgot that I was going to have R2 be the one to bust Finn from his
cell, and then when Finn went off to start his rebellion, R2 and 3PO
would go hack into the First Order’s computers to delete the memories
they stole from R2 (they didn’t find anything on Luke because Luke put a
Force lock on those files, the way a holocron works.) And then he and
Leia would find each other.
