Damn, that closing celebration matte has never looked good, has it? I can see why you were torn... there's not a lot to work with. That original matte looks horrible in the original film print and has always stood out. I have to say that I would probably prefer the way it was in 1.0 since darkening the sides is hugely distracting... I mean everyone knows that scene and how it's supposed to look. It just appears to be noticeably altered and will be distracting when viewing the film. I sympathize, because this must be a tough, touch call.

If it were me, I'd actually go with the SE shot as it's not an offensive inclusion and it looks so much better and more natural in HD. Have you considered freezing the SE shot to create a new matte? That way the guards wouldn't be moving and would emulate the original shot, but wouldn't look as horrific.
