Sure, paperkey supports piping the output into whatever code generator you like: gpg --export-secret-key mykey | paperkey --output-format raw | your-bar-code-generator However, 2D bar codes have some of the problems that paperkey is intended to address. You need a 'thing' (a process, a device, etc) to read them, and part of the point of paperkey is that it's supposed to be the backup of last resort, and thus readable by a human without any special hardware involved. You could also back up your whole key via a 2D bar code (without using paperkey at all) but then you're backing up a lot of redundant data, giving you a larger image. Of course, this may not be a big deal if the intent is to scan it back in again rather than type it back in again.
