For ANH, I'd like to see at least 3 audio options:
- mono mix
- hairy hen's 70 mm 5.1 mix
- theatrical dolby stereo mix (this has been re-created, right?)
Anything else (like the 93 mix, recreated 5.1 mix, etc.) is gravy
For ESB, I'm not as familiar with all the available mixes. But if I had to throw something out, I'd say:
- 85 stereo mix
- 93 stereo mix
- re-created 70 mm-lite mix (5.1) using 97 SE soundtrack as a source - I say "lite" since a true 70 mm mix would have a different runtime
