To finally, finally, finally, finally do it right, and do it without worrying about the new editions...here's what I'd do if things were available:

Theatrical in Dolby Stereo, Dolby Stereo 70mm, Mono (for SW only)

Theatrical 70mm version (2.21:1 blowup) in Dolby Stereo 70mm

The 70mm mixes could be presented as they were pretty easily or slightly reformatted into a standard 5.1 mix.

SW: The 6 channels were done this way originally- Left, Center, Right, Mono surround and two baby booms on each side of the center channel. These only augmented the bass instead of being discrete. You essentially would just need a 4.0 channel mix and a sub to get the idea. If you added in two speakers you could recreate the full experience but this would necessitate a 6.0 mix or a 7.1 receiver where you could just turn on extra speakers as mirrors cut out the treble and place them accordingly.

ESB and ROTJ were done in stereo surround without the baby booms so this would be much easier.

I think the 97SEs should be included as well. Fresh scans of just 35mm should look stunning-especially if the full DTS was finally included. These knocked your socks off back in 97 theatrically. And there were even some 70mm screenings too.
