We have! Hotch/Rossi is a bit of a comfort pairing for us, and we've actually written on long (about 75k) AU-ish fic, as well as a handful of others. They're all at this tag: http://community.livejournal.com/geekystudmuffin/tag/pairing:+hotch/rossi

I had always said I wouldn't write this pairing, and I obviously have, so I'll never say never to it again, but right now we don't have any plans for more. I guess you're all just lucky I adore Mcgarrygirl78. ;)

It's very gratifying to know that regular H/P shippers enjoyed this, though, so thank you very much! :D
