Yeah, Matt/John works really well. I still think Matt/Lucy could be hot, but I'm equal opportunity like that. ;)

And yes, there would be wall slamming. Matt would be oh so confused, and John would be oh so sure.

I was thinking more "Matt would be oh so turned on," but whatever. :) Really, the wall-slamming is what's important. I'm a big fan of wall-slamming. *cough*

All I've found for the fandom is hard4brains, and I'm thinking this fandom is just begging for Yuletide. There's a few good fics and a large number of mediocre ones, but that's pretty much what I expected. If you don't want to run through them all (although it doesn't take much time, to be honest), my favorites were probably this and this. Oh, and this one is pretty good, too. :)
