I would like to remove Palpatine and Exegol. My version would focus on the way-finders which Palpatine used to search for the origin of the dark side. During the fight in the Deathstar the FO would attack the Rebellion and the civil fleet would join them. After Bens defeat Rey would transmit the code to surrender from Bens tie-fighter to the FO. The movie would end after Ben and Rey destroyed both way-finders and their weapons.
Yeah, I was thinking about something like this, too! I’m currently trying to work this out, but basically I had the same idea like you.
Hopefully there will be a lot of cut scenes to add once the movie gets released, or maybe one could add some unused material from elsewere.
