Greater thickness will certainly increase the dampening, but I'm not sure you need material where the sheet metal is already pretty stiff.

I follow what you are getting at, and I'm sure you are right about that, But the tricky part may be figuring out how close from the edge to stop your mat and still be able to control the resonant frequencies you are looking to contain. That in itself could be a very tricky proposition, and would certainly take more research than I would be willing to put into it. I would say, since panels are off, and mat is in hand, go 100% and leave no question.
