For the limited times they used it in TRON: Legacy it was fine. It won't hold up for use on main characters in feature films.
Just let the franchise die a noble death. Between GL's constant changes and your suggestion, Star Wars would become a shadow of itself and quickly turn from beloved sci-fi classic to cash cow. Some may argue it already happened with the PT but I still think there was heart in parts of the PT.
If they do anything with a post-ROTJ storyline, I would not mind a cartoon similar to Clone Wars. Maybe not that style of animation but I think you can find voice actors to fill Han and Leia. Hamill can still be Luke and he has voice acting experience.
