Sure, why not? I just ordered a BMX chain ring that's basically an aluminum disk with teeth around the outside, a biggish central hole, and a smaller drive hole. I'm planning to modify it into a custom ring for a 50.4 mm BCD cranks, but other options are available. I'm sure it would be easy enough to drill it to hold another chain ring.
BMX rings are for 1/8" chain, which may complicate matters somewhat. But you have a Dremel, right?
