This reply literally made me laugh out loud, you're the best.
I was going to try to contact you last night when I posted this thread, but I decided to wait until the morning, and you bloody beat me to it!
If you're up for it, I would be absolutely honored to contribute. Just tell me what you've got left to work on. I'm pretty familiar with the code from the mw2 version at this point, and would be excited to get a mw3 version going. If you'd prefer, I can set up a private repo, so the source won't be available just yet.
Seriously though, you're awesome.
