I don't know anything about the metal band and whether that affects the sound...I don't believe it does simply because it's on the outside of the bore (the bore itself is what really affects the sound). Somebody correct me if I'm wrong!
Yes, if you switch bells around keeping the exact same reed, oboe, emouchure, etc, you can get quite a different sound. If you know some other people that play oboe, give it a try!
I don't personally switch around my bells a lot, simply because I don't own a lot. However, my teacher does it for various reasons, sometimes it's to try and improve a certain note (e.g. 'drunken E' on Lorees), sometimes it's to get a certain tone quality, sometimes it's to improve the intonation in a certain register (I think I remember him saying that the longer the bell is straight for before it flares out, the higher the upper register will be in pitch. It was something like that, in any case he put the two different bells on and the difference was huge!).
Sometimes different bells won't fit properly, but often they go on just fine. I know my teacher wraps cigarette paper around the cork (of course he takes the glue part off first! He just licks the cigarette paper itself so that it sticks) of the bottom joint if the bell is too big.
