What would've been ideal is George stepping back and being the over-arching supervisor of everything, writing the story outline for the PT and the post-Jedi EU but letting other screenwriters, directors and authors fill in the details. Instead he was hyper-focused on the PT and paid little attention to anything else.
What would have been ideal is if Lucas had just washed his hands of the franchise altogether and started working on something new.
