I have a friend who's dad owns the torque engine and we were messing with it and came up with this: (mostly him, he's good with torque)
Door 1 had a camera 1 on it facing outwards, and had camera 2's view mounted to it, and same for door 2. So it was like Super Mario 64 except you could see what was on the other side in real time.
But your idea isnt possible unless you seriously redo the engine.
