I don't know how much work you've done on the soundtrack so far, but I'd suggest using the '97 SE soundrack (70mm) for most of the edit. And then all you'd have to edit out would be the "Alert my Star Destroyer....." and the one sound effect of Vader shuttle landing, and "you were lucky to get out of there." Cause the 97 soundtrack is of higher quality, it should easily match the 2004 print, and editing those pieces above would be way easier then trying to correct music cues.
That is unless you want the 35mm soundtack for a reason I'm not aware of.
