This isn't too bad of an idea actually, the only real flawI can see is that I don't believe Peter knew Maxis before Group 935 (which was set-up several years after 1917, during WW2) but who knows? Nothing says they weren't old friends and that could be why Peter was picked to be a part of Group 935. Good theory.
