Band clamp at muffler hanger location?

I've been reading this thread on band clamps. Exhaust Band Clamps Since it's an old thread I thought it best to start a new post. If this question has been answered please link to the discussion.

My question has to do with the TTI muffler hangers. The hanger has a traditional muffler clamp incorporated into it. It serves as the muffler hanger and the muffler to tail pipe clamp. Using a band clamp on the other connections seems like a waste of time if I'm forced to use a traditional clamp on the back of the muffler. Has anyone incorporated both the TTI hanger and a band clamp in that location? Basically the TTI hanger would only be there to act as a hanger and not to clamp the muffler and tail pipe together. Maybe put a bend in the TTI hanger so it makes contact with the tail pipe but not the muffler? Then both could be used.

I have 3 different mufflers to try. A band clamp would make swapping the mufflers much easier.
