I was bored and dropped Qui-Gon into ESB and Jedi, just an experiment to see what it would be like (not really for the OT edits or anything, just boredom and to see if it could be done). Putting him back in some small way into Ep 3 is easy enough.
And so far, I just had the Dooku stuff downloaded from the net, though I know they have Xbox ripping software out there. I haven't worried about it too much yet. Nov 2nd may be a different story.
Another thing I noticed is that if you watch 1-3 as a stand alone trilogy, it works better to have no Vader and kill Anakin. The birth of Vader just feels tacked on... It's a loose end... Like a big TO BE CONTINUED slapped on the credits. After doing all the horrible things Anakin did, he deserves to die... even if only to stay dead for a film and a half.
Plus, my new "scene that explains it all" in Jedi, has brought chills to the few who have had the fortune to see it in rough form.
