Question rattling cat

My one high flow carsound cat has had the packing around the honeycomb material blow off. As a result, the honeycomb material is now rattling around as a whole inside the converter. I was wondering if I could compress the converter body in a little just so that it keeps the honeycomb from rattling inside.

Do you think this approach would work or am I wasting my time? This is my third cat that this has happened to from bottoming out and then the packing material blows out.

This might not help you any man haha, but this is what happened to me.
My passenger side cat did the same thing, piece broke off and rattled for awhile on the stock cats....didnt think much of it...about 3 months later I decided to gut the cats and put a pipe through them....did the drivers side fine and put it back on...cut the passenger side cat off and looked in it...it was completely cleaned out..better than i could ever clean one...all my honeycomb material had broken up and went back, hung up in my magnaflow, and ended up causing me to get a new muffler right after that...I would change it out..
