The one issue I still have with this would be the exhaust moving about an inch...doesn't seem like there was THAT much play in it, but I can't think of anything else that would cause this to happen.
-The interference was also not noticeable during installation possibly because we pulled down a bit on the exhaust, and stressed the hangars. Given they don't have a spring-like rebound rate, while the car was on the lift it didn't interfere. As time passed, it might have pulled it into the canister.

I'm obviously not a professional so don't laugh if this sounds stupid.
But how about using a longer rubber hangar that is long enough to compensate for the contraction so that it would remain in the same position as when you first installed it. I think this would be the easiest and cheapest way to resolve your issue with the cannister interfering with your exhaust pipe. I think as long as your pipes don't come in contact with your cannister you shouldn't have problems with exhaust heat melting the cannister again.
