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. -- http://www.ernest.isa-geek.org/ "Ignorance is mankinds normal state, alleviated by information and experience."
