Ah! I see what you are trying to say. Well it's definitely something they can do. I've heard rumblings that all of the original sfx shots were recompositied for the SE in the 90s and the cgi additions were created and added later. If this is true, all they'd have to do is scan those snippets of film and splice them in with a scan of the SE 97 negative.

There are of course many here who feel that this would not be the original film since the original effects and wipes are re-created and is not a true historical restoration. However, there are many people who want the OT but not the mattelines and garbage mattes and generation loss (speeder entering Mos Eisley). We shall see!
