I think the constraints for these fingerprints are: 1) You don't have free choice of strings (like a password generator). Instead, you can only evaluate a "scoring function" on candidates produced by SHA256(pubkey + 32-bit counter). 2) The scoring function needs to be fast. Ideally it would be faster than a single SHA256 compression function (which might be accelerated via GPU or special CPU instructions).
