Roll a rim out of 1/4" x 2" flat bar and weld it on the back, to make it shaped like a real "gong".
Build a cowbell or school bell out of ar500.
Guess you have to build first then temper though.

How about mounting another plate touching behind it.
that's what I did with one of mine. drilled a 5/8s hole through it and a piece of mild steel about have as thick and put a 5/8s bolt through them both with a few washers to separate them and double nutted the bolt leaving it fairly loose. You could probably do the same by just hanging a chain behind it with a 1/2 of space between them.
Good drummers' cymbals are made of fairly exotic alloys including copper and silver and are basically phosphor bronze. They are also very thin. Most any centerfire would leave holes.
