Teen Leia running around Alderaan and being taught how to be a kick-ass fighter by her aunt. It would make billions!
Or maybe teen Leia having a romance with a 400-year-old Force Vampire or something.
During the Alderaan food shortages, teen Leia is forced to fight in a some kind of archery tournament.
The possibilities are endless. We haven't even got to teen Leia and her stoner buddies and pet dog driving round Alderaan in a van and solving mysteries.
