Sure Slartibartfast! All we need is a great welder and Robert Downing Jr. to be in a sharing sort of mood, I don't see why not. Welllll, I take that back. Silver Surfer could possibly be made of mercury and that might not work well with Iron Man's metal; but, it's worth a shot. The living situation could spark a bit of an argument too. Having them both in the same suit at the same time will definitely be cramped.. Unless Iron Man renovated his suit so 2 would fit comfortably. Knowing his character, that is a huge "IF." But Hey... they'll figure out like real men and decide who will be driving. I say, 2 Super hero's for the price of one. Go For It!
