I like the idea of just cutting out the Emperor coming to save Anakin and end it with Obi looking down on Anakin (cut out Obi walking away). That way if you do the funeral on Alderaan scene it would appear that Obi brought Anakin's body with him to be buried on Padme's new home world... which leads to:

- has anyone considered the idea of Naboo being destroyed (if not like Alderaan, then the surface of the planet laid to waste)?

I also like the idea of not even showing Anakin becoming Vader... just end it with him burning (take out the last moans so he goes quiet, ie. audience thinks he's dead) and Obi looking on. Then (as Muddyknees I believe wrote) you see Vader in ANH and go with it. That way when you get to EMPIRE and Vader does the reveal, the kids go "Holy Shit! I thought he was dead!" Combine that with the whole "fake Harvey Dent-ish" funeral, and it makes Obi Wan and Yoda a little more dimensional as characters.

Overall though... these movies are just a mess. Editing, acting, voice work... this is going to need an entire make-over, with new voice acting and editing and LESS SPACESHIPS LANDING. Jesus Christ, these films would probably be an hour or 3 less if you cut out all of the landing and taking off crap.
