Well, first off you'd want the coolant loop that heats the intake air to be on the radiator size of the thermostat to maintain fast warm up. Second, your engine sucks so much air through it I don't think you'd see a ton of warming from running this extra loop. The exhaust is so much hotter, and its easier to pull heat off by running some ducting near it.
The stable water temps may be an asset if you run into pinging from too high of temps. It would be easier to control a steady temp with coolant versus exhaust heat I would think.
