I still think that tapping in to the heater core lines, installing a small ball valve and two quick connect fittings to connect to your water heater would be better then changing the hood around to capture heat, as it would put the heat where you want it via water lines and you would be using the water pump that is already on the engine so you wouldn't be adding more then about two pounds of weight for the quick connect fittings and a ball valve, it would be a fitting before and after the valve in the same line going to the heater core, very simple way to pull heat off the engine, it would also allow you to reverse the setup for warming the car up quickly in the morning by adding an electric pump inline and pulling hot water from the house and warming up the gas engine with it, getting rid of cold starts.
