It's tempting to want to include as many tracks as possible, but there comes a point when it's scarcely beneficial to keep putting in more mixes that differ from each other only in nearly inconsequential ways! And of course, anyone who is sufficiently motivated could always make their own custom version muxing the processed video with the audio tracks of their choice; it's actually not that difficult, just a little time-consuming.

I don't have any plans to insert deleted music in ESB. I was watching the Editdroid disc with the isolated score recently, and came to the realisation that most of the parts they cut were ultimately best removed. That isn't a remark against the music, of course; the entire score is brilliantly composed. There are a few things that I think might have been better left in, such as the dangerous low piano motif that marks the first appearance of the Imperial walkers, and the part when Han and Chewie find the probe droid, but those are only small matters. None of them made me feel as strongly that their deletion was a mistake as did the RotJ cue I mentioned (the whole scene somehow falls flat without it). A lot of the parts they cut out are somewhat loud and distracting, sometimes too triumphant--removing them makes the ominous cues that follow become that much more threatening.

Speaking specifically of Luke getting his lightsaber and seemingly defeating Vader in the carbon chamber: I saw a youtube video of the Dooku/Yoda duel in AotC that had that ESB cue inserted into it. It was amazingly effective! The powerful rendition of Yoda's theme brought the otherwise ridiculous scene up to a whole new level entirely, and it was just the right length, too. I thought that was really interesting . . .
