If I was served up a ANH:R HD version I really would not want to see anything changed to much from what it already was... I know people complained about a few things like the lightsabre needle or music added to the light sabre duel or what ever...
Cue music

Screw changing it from what it was... It blew me away...Amazing
I would like to see Tarkin before DS explodes and I would like to see Boba mooching around on Tattooine.. But I can live without these
That is about it, all changes should stay intact end of in my opinion..
In fact I like it just the way it is and if it was reiterated it should be very very close to what it was in the first place.
But I feel it would be very hard to duplicate that magic of when it first appeared... That is perhaps out of reach for second dibs
