Interesting concept. I would assume that a block heater would warm the water in the engine sufficiently to keep it from freezing. I would recommend using a block heater on each side for plenty of heat, and redundancy....that's what I used to do years ago when I wanted to be sure my truck that never saw the inside of a garage would start when it got cold.
