Why is the oil exchanger out of the question? I don't see how it could be any more dangerous than a muff.
My plan is to duct either a radiator or the oil cooler so that I pick up cabin air both in front and behind the heat exchanger. The cool air pickup in front of the heat exchanger will run through an icebox, and then both ducts will run into a cabin controlled 'mixer' to give the maximum in pilot/passenger comfort.

With the hot oil exchanger, I was remembering Chuck Harbert's experiences with two ruptured heat exchangers. The lower pressure of the hot water would be the lesser of two evils. Also, I have had experiences in cars with leaking heater cores. The big problem there was they fogged the windshield. Still, that could be handled with a towel, or any handy piece of clothing obtained from the co-pilot or passengers. ;-)
