There is no 70mm stereo restored soundtrack for Empire or Jedi, since we don't know for sure what those 70mm tracks sounded like. (Plus, it's possible that the video for the Empire 70mm version was different, as well.)
The 70mm track Hairy_Hen made for Star Wars is, however, a restoration made by comparing an in-theater 70mm recording to the 1993 mix, so it's as close to original as we can possibly get. There are no music edits to this (though I'd love to see the Bantha/Tusken Raider music cue fixed as it is on ANH:R - it bugs me every time I hear that music edit after seeing it fixed).
I like the idea of the music-fixed Empire 5.1, but it'd be nice to have a 5.1 upmix of the 1993 mix with the speeder sound effect restored and the added 1997/2004 LFE track (edited to match the theatrical mix, obviously), but the music left alone.
I'm torn on the restored cue in Jedi, but I do like the scene with the music. I'd like a pure 5.1 upmix of the 1993 mix, though (with the LFE track from 1997/2004 added as in Star Wars and Empire).
However, as these music-edited options are 5.1 tracks, which never really existed for the theatrical versions anyway, the purist in me can let it slide.
