That would be most welcome, right now the only gpu projects which
support wpa are pyrit (dead) and oclhashcat (closed source).

There are many reasons why this is good, right now we advocate using
john to generate a wordlist to crack against, no point in piping the
output from john into aircrack-ng when you can likely build a much
faster cracker anyway.

I agree, please don't abandon your work.
I believe what needs to be done is a way to simplify cracking wpa with
john. oclhashcat has some odd format it wants, a patch was accepted to
aircrack-ng to output that file:
aircrack-ng -J [hccap_name] [cap_clean_file]
I would happily extend to you the same courtesy, if you find that the
hashcat output format is unacceptable. I would also be willing to
(attempt to) negotiate a format change so you could share an input
format with hashcat and I don't need to have different output formats.
Thanks for your hard work, we are all pleased so please do not feel
deterred.
