You could always go with the classic memory wiped youngling at Luke’s temple theory.
I certainly could but I wanted to know how far could I get in a radical edit of the sequels without (mostly) new footage and just dialogue/score tweaks
Rey being either Luke’s daughter/apprentice crossed through my mind a lot of times, then I thought that Rey should be the apprentice of a male Jedi (her father in the theatrical film) but her mother was always with them and it would be a real pain to remove her (that’s when I thought about making her Rey’s master and now, I thought about also making her Luke’s first apprentice instead of Leia)
