How are you handling that sequence in Rise then? If the Saber isn’t tossed in Last Jedi, there’s no reason for her to toss it again, spurring Luke to appear.
Does Rey still travel to Ahch-To? I know that TIE has already survived complete destruction once before, but it’s less plausible for Rey to escape Ahch-To after burning it. And then Rey flies a damaged X-Wing to Exegol, Kylo walks by it, and Rey leaves in it and arrives back at Ajan Kloss in it.
If you can successfully adjust all that, I’d be really curious as to how (I have separate issues with Rey using his X-Wing and destroying the same ship twice).
