Remove Luke element from the film and replace map to his place with map/blueprint of the superweapon (which is film’s defacto focus anyway) and you have completely identical film.They’re both mcguffins but unless that map/blueprint trained and was betrayed by our main villain and is presumably going to train our main protagonist I wouldn’t say they’re identical.
Main villain could have betrayed Luke just the same and Rey could later be trained by him just the same, if he was not missing/hiding in the first place (i.e., no “finding Luke” useless filler).
