Personally, I've always loved the Cloud City window & balcony SE additions; actually, they're about the *only* SE additions that I feel strongly about keeping. IMO, they make the place feel more like an actual city on an alien planet and less like a movie set. Granted, those reflections are horribly done and need fixing in the worst way, but it seems to me that replacing the whole shot with the enclosed hallway would be throwing the baby out with the bathwater...
