Sounds great but all this 2/3 year old nonsense is a lesson from the Prequels of what not to do. On Paper this sounds amazing but reign in Luke training loads of Jedi and instead have him discovering just one (Rey) who is embracing the Dark Side based on the lessons of Maul.
So twist the movie on it’s head, Maul = Obi-Wan, Rey = Luke but we’re focusing on the bad guys. However by the end of the 2nd film, Luke faces off against Rey in a duel thats the opposite of The Empire Strikes Back and Luke’s words to her make her question her choices of embracing the dark side.
Then come the end of the 3rd film it is actually Rey who helps the Jedi rebuild - all that stuff with 3 year olds leave off camera.
