I'd love to see an EE. I think the scenes are a bit too rough to really seamlessly integrate, though. Maybe the new DVD will have better video. It would be nice if they bothered to remaster it and put it in anamorphic like a few DVDs do.
I don't think the extra footage would bog down the pace. Not for fans who've already seen the movie, at least. I think I am the only here that thinks this, but I believe that the second time you see a movie, the pacing is a whole different animal. It can afford to be slower because re-watching a movie is such a massively different experience than watching it for the first time.
I also think many director, producers and editors really feel the need to 'keep it around 2 hours' when in a lot of cases, it's not needed. 2.5 hours can be better, depending on the story. Or 3 hours could be worse if it's a molasses-paced piece of crap like The Good Shepherd or something. But that's just my opinion.
