I recently thought about doing a very similar mod. I was thinking of taking the return line from the existing heater core, and cutting it. Then run one side of the return line to the intake of the air box heater core and the outlet to the other side of the return line. Basically put the new one in series with the return line from the existing heater core. To control the temp, I would use a flapper valve in the airbox, controlled by a push/pull cable. No need for a flow valve.
