Oh! I had a brilliant idea for you in the middle of the night! (it's when I have my best ideas actually and bonus I remembered it)I have searched the internet over and I don't think I've ever seen an AU Cam/John story. Now I know half their appeal is that they're both pilots, but I can find McShep AUs anywhere! (in fact AU McShep is the only mcshep I read. Tell no one!) But I haven't seen an AU Cam/John, of course I've seen stories that might mention them in passing or where I guess they were at one point but no longer are. And while your John on SG1 actually is an AU it's not like completely different direction AU. Like if they were doctors, or FBI, or pirates ("wtf renee, pirates?" "Shut up I'm creating!")or hell they could be viper pilots on Galactica ( "That's an even worse idea then the pirates!" "Yes so I embrace it!")! But I just thought it might be an interesting prompt for you.
