Is there any way to get a replacement PDGA mini with my number on it?

Answer: No
Reason: Everyone would want one and it would throw a wrench into the production line. I read it's part of their contract.

huh? what production line? where did you read that?

I called the PDGA about buying an extra mini once and that's what the girl told me. They are made in large batches with no reprints ever. So, no I didn't "read" it, I heard it.
