His backstory is actually pretty detailed thanks to Clone Wars I would say. any future Boba movie will not contradict his Jango/Clone origins.
So much time has passed since those events and the OT era that he's basically a blank slate as far as the movies are concerned, especially post Jedi. Not to mention most film goers are probably unfamiliar with the cartoon and so it'd be weird to build on them in any meaningful way. They won't contradict his backstory, but it won't matter enough anyway.
