Robert Rodriguez? Now that would be a sight. Maybe a script by Quentin Tarantino? He has to be a Star Wars fan. Although he may struggle to make a script with a preferable PG rating. In any case I think Lucas should tell others the story and let them create it with oversight by him.
Kevin Smith script.
He feels for the working man who didn't ask to be brought into a war and yet died when the Rebels blew up Death Star II.
