Would that recontexualised TLJ include Luke vs Kylo? Cus it seems that would have to go, and have the climax be Rey & redeemed Ben killing Palpatine, followed by an edited Tatooine epilogue with Ben staying there in exile.
Yes… I’m unsure about this part. I agree this new TLJ would end best with the Supremacy. Maybe after the two beat the guards, we show the shots of their hands to force-pull an empty Raddus into the Supremacy, turning the Holdo Maneuver into the big finale beat.
Crait I think should be moved to the end of this new TFA. All hope seems lost, Palpatine is back, so they retreat to Crait and appear defeated when Luke shows up (for the first time) and saves the day. He doesn’t die this time, so new-TFA will end with the heroes escaping Crait and Rey going in search of the recently returned Luke.
OR if that makes TFA too long and new Ep 9 too short, you could move Crait to the beginning of Ep 9. Not sure how that’d work though.
Of course, this can all be avoided by just keeping Kylo evil as TLJ implies. He killed Palpatine and will continue on, but Rey will eventually beat him or something. However, I’m personally not a fan of that ending for Ben.
