I was considering doing something of that sort, but pretty much abandoned the idea because frankly, it's just too much of a pain. Not only are there overt editing differences, but apparently, there are missing frames every time an optical composite was re-done for the special edition. You'd have to upmix and patch in sections of the '93 mix for places where the edit was changed as well. Considering that even different audio mixes of the original versions don't easily synch to each other, one so altered won't be made to fit the original film without a lot of tedious work. It could be done, of course, and I would be interested in such a thing if it was, but it would be difficult.

The '97 mix does sound rather good in 5.1, but I think ultimately I still prefer the '93 version since it is closer to the original 70mm mix, and has greater dynamic range and sound quality.
