I like this idea a lot…I always hated that scene of Rey lifting the rocks with such minimum training as its just makes her look so OP with no explanation. I always wanted an edit to appear as if Luke is lifting the rocks and not Rey. However your idea ties into TROS themes so it’s a lot better.
Agreed. The scene would be much more believable if the film took place a few years after The Force Awakens instead of immediately after.
