That was my "idea," but again it was more of a fun experiment then an actual suggestion. I admit it is an intriguing propsoal, but regardless of whatever role Dooku would play in Episode I, wouldn't it undermine all the reasons for removing Sidious except for the rather obvious Sidious=Palpatine connection. So although Dooku in Episode I via an obscured Sidious hologram and LotR dialogue was in fact my idea, but as for fitting it into the story, I really have no plan to speak of. I would encourage my esteemed colleagues to try and devise one though if the concept is of interest to them.

Now, in one of the few mentions of ESB in the thread, I once again turn your attention to sepharih of the Jedi Council Discussion Boards. I thought it would be best to explain the folllowing clip in the words of the editor himself:

First I would like to give Neo_MP5 credit for his help in this. A week or so ago he gave me a couple of clips to showcase his adding of Duel of the Fates to Luke and Vader's duel on Bespin in ESB. The clip i'm about to show you is from the very last part of the duel during the "big Reveal" scene.
One of the best things Neo_MP5 did in his edit, which I hope he will showcase here when he's finished with it, is that he didn't just layer Duel of the fates over the entire fight, but instead restricted it to a very subtle motif that would occasionally play during key moments, whilst restricted the majority of the added music to a darker more ominous track.
During the last part of the fight, however, duel of the fates spins out in all it's glory and the effect is very impresive.
The begining of my clip is structured exactly like his is, and it only variats after vader knocks luke down on the catwalk. I was personally slightly dissatisfied with how the music was cut after that point and so I decided to do my own variant of it. I PM'd Neo_Mp5 with my version a day or so ago but I haven't heard back from him yet, So I decided to just go ahead and post it here.
Also, it changes one more thing. Originally when Vader revealed his identity to luke it was, of course, designed to be a huge twist. It was as much a revelation for Luke as it was for the audience, but now when watching them 1-6, everyone knows that it's coming.
So I started thinking about it, and I eventually decided to see what it would look like if the twist factor was removed completely, giving it a track that was remniscent of Anakin as well as building up to what was about to happen. Now, I have added instead a track from Episode 3, and the scene now is no longer designed huge shocker, but rather an emotionally climactic moment between Luke and Vader. I'm not sure what the reaction too it will be, but I know that this is going on my personal cut of the trilogy.

I think there is some definite potential in a musical alteration along these lines, particularly in the "I am your father" portion. Of course I had that music in mind for Obi-Wan's death, but I'm sure we can come to a reasonable compromise through discussion. Duel of the Fates matches up surprisingly well too, but I doubt many here will be fans of that change.
