It’s cool and all, but if that were in the movie it would need to be followed up on. I don’t think it’d fit into the movie as it is.
I was just thinking it follows up nicely with Luke on Ahch-To and him showing up to help Rey on Exegol and then later being on Tatooine.
Probably won’t work on this edit but could be interesting if someone did something where Luke force projects Han Solo’s memory to Ben in order to redeem him and pushing him todo the right thing.
