I don't think the cost would be that great compared to a block heater and the cost of running a block heater, also when you get home you have 195F degree water in your engine block plus the mass of the engine being that warm.
The two largest costs that I see would be a small pump and a heat exchanger, plumb it all together with pex in the house.
I'll see if I can talk my co-homeowner in to letting me do this, but I don't think she will.
