Aziraphale/Crowley, Good Omens crossover

So I've been reading good omens, which is awesome, and would love to see some fics about Aziraphale and Crowley in the SPN universe. Crowley doesn't nessecarily have to be the Crowley from SPN (though that's fine too). In fact, it would be quite funny to have both of them meet and GO Crowley would be all annoyed at this upstart using his name and trying to muscle in on his reputation for being the most approachable Demon in Hell. lol.

Or hey, any fic where Aziraphale comes to Crowley's aid if the Winchesters or Cas, or Bobby turn on him for being a Demon. Or just... anything at all. any other pairing is fine, I would just love to see the SPN characters reactions to an Angel and a Demon and their Arrangement.

I have read the Arrangements Series... which is friggen awesome, so I need more!

Hurt!Crowley is always a plus. (and I would never say no to Gabriel coming back, or some TFW)
