New Badges?

I wanna get some new badges for my accord, but i don't think it will fit on the back, b/c where the stock badge is now, on my 97 Accord, is kinda concaved, like a C. If i put a flat badge on a curved surface, I think it'll fall off. The stock one now is thicker in the middle, so it stays flush with the surface of the car. Does anyone now of to fix this/ dealt with this before? I would appreciate any sort of help...
