'Fixing' some of the choppy music edits in Empire is on my list of things to do after I get the 70mm 5.1 sorted out (which hopefully can be wrapped up today). This would involve substituting appropriate sections of the '97 SE into the 1993 mix; notably the transitions from Dagobah to the Imperial fleet after the cave scene and after Yoda raises the X-wing, and the longer version of Boba Fett's departure that ends with the scene change to Vader and Luke, rather than cutting off when Chewie begins firing at Slave I. While I'm at it I would add the missing snowspeeder effect.

While these changes cannot be said with certainty to bring the '93 Empire closer to the 70mm mix, since no one truly knows whether they were present in that version or not, to me at least they would make it a bit more aesthetically pleasing by using more of the music as composed. I have no plans to revisit the audio of Jedi; my previous version contained the deleted music from Obi-Wan's appearance on Dagobah, which was not on any official mix, but I think the scene benefits from its inclusion.

I would keep these music edits for Empire and Jedi confined to the 5.1 versions, since however good they sound they ultimately reflect my preferences and are not strictly authentic. The straight '93 mixes of these should be sufficient for 2.0 playback. I would recommend against using the 5.1 SE mixes as a majority source for the audio of the unaltered films, because they contain numerous 'flashy' surround effects that are far too loud compared to the rest of the sound--and the 70mm versions utilised a mono surround channel, not stereo surrounds as on the SE's, so the original design would be more accurately reflected by '93 upmixes.
