My two cents, which in Canada will soon be rounded down to zero cents due to outmotion of the penny, is to first try making stacks or x-hats.
Example of stacks:

Obviously you don't need to have $1000 worth of cymbals to do it but it shows you what's possible. Try different ones on top and bottom, flip them upside down, use two, use three, tighten and loosen the wingnut, basically there are no rules except to quote Bob Gatzen; "If it sounds good to you, then it sounds good.". Right now I have a keyholed (not by me) 8" B8 splash over 14" AAX mini china over busted (again, not by me) 16" AAX stage crash. The sound is somewhere between a very short and quick china and a less 'jingly' chopper.
Example of x-hats:

Here they sell them as a set but you can make x-hats out of any cymbal you want. Since your cymbals are somewhat disposable you can just jam them on a stand or arm without worrying about keyholing them. Again, try different ones on top and bottom. I was toying around with the 14" china under 14" AAX stage hat top for regular high hats, sounded neat.
If none of these options strike your fancy, like wildbill said, break out the power tools.

A drill and a good hole saw FOR METAL will take care of that for you, along with a file/sandpaper. Boy howdy, cymbals are sharp if the edges are left raw.
A drill and some rivets will give you this:

It's not all necessarily 'original' but it's a good starting place.
