The scene is unfinished and would need work to address temp effects. As I’ve said I think I agree with RJ’s choice to cut the scene (despite liking it) to leave things hopeful between Luke and Rey before their falling out. Side benefit also, with Luke being truly alone.
And in this case, unlike with Ep3, there’s no drastic, alternate-universe sort of divergence. I respect your question, but I don’t think so for this one. 😕
