I'd be interested in a set. I was considering doing the same thing. If I were you I'd use mdf to make a set of perfect templates, then use double sided tape to stick an acrylic (or more mdf) piece on, then take it to a router table with a template bit, and finally to the drill press. You could whip out a couple sets an hour.
Acrylic is more expensive and looks nice, but I've seen people use a natural varnish or poly on mdf and it looked really good.
