I know this is more a VFX (a really hard one to do actually) change, but what if there was an version of this movie where luke uses both of his lightsabers?
I really miss the green one and it would really be awesome to see he fighting kylo with his green. But the symbolism of Luke holding the Skywalker saber again after refusing it to Rey is pretty good to me and it seems like a waste to not have Luke using the Anakin’s saber during the movie.
And would be the coolest thing ever seeing Luke with the green saber in a hand and the blue saber in another, like Anakin in Attack of the Clones.
I understand this edit is a quite impossible thing to do, but if someone talented like jonh done something like that, it would be really amazing and it’s a shame that Rian Johnson don’t think of something like that because it would BREAK the theater
