Fans can nerd argue all they want about Boba Fett, but he looks cool and honestly that's really all that Star Wars has going for it. Don't do a movie with him as the focus of Episode 7 or all that, but you can get some mileage out of filling in his journey until he shows up in Empire or have him blow his way out of the Sarlaac and "Kill Bill" his way across the galaxy.
Personally Id love to see them do the Jon Wagner and Cam Kennedy Dark Horse comics from the late 90's as an animated direct to video thing or something.
Side note, I did this page just to see if I could throw together a painted page with some text. Ive got a project I think this would work really well with.
