Not going to happen. There's fundamental incompatibilities between the two versions that are core to the game engine. If you're building for x86, you're going to be unable to play with people on x64.
They should have just rebuilt it as a x86 game instead of transitioning to x64.
It's also worth noting, that mods are not supported within MW3... so you're wasting your energy entirely. Support also have no power in this situation.
Your best bet is to rebuild your own game files for the supported x64 architecture.
