To be honest, I wish I could just cut out that entire part of the movie with Obi-Wan. It is completely pointless and literally serves no other function than giving Obi-Wan something to do while Anakin turns bad. But I'm already removing Yoda vs. Palpatine. If you take this out too, what is there left?

You're right, there's not much left. If the Doctor Maul idea (which I love) doesn't work out, you could leave out large portions of both Episodes 2 and 3, put them together, and call it a "Double Feature." Just an idea.
