I think I am leaning towards using the stereo mix again, because I do like the way it sounds more in that version. It may work well enough not to be an issue if I edit in and out in the right spots and take care to match the EQ and level more precisely.

Despite having switched to the '85 mix for the replacement sections in the first movie, I did still keep one part from the '77 stereo (the explosion that convinces C-3PO to get in the escape pod) since it sounded more robust than the '85 did for that particular effect. Even though the stereo image does change, it's quite difficult to hear the transition in that spot since I was very determined to find a way to make it work, and I did. ;) So I'm hopeful that this will be equally successful. I won't know for a couple days since I'm currently mixing some music for a friend, but I'll get back to it as soon as that's done.

This would, of course, be easier if they had made '85 mixes of ESB and RotJ with full stereo width as they did for the first movie (or if the '93 version weren't inexplicably missing the crash sound to begin with). Oh well. I'm not sure if a hybrid version would be possible, but I'll look into it. Perhaps if I extracted the sound from the center channel of the SE and blended it into the '93 directly? Hmm . . .
