If you really want air warmed by coolant before the thermostat opens then plumb in a second heater core off your exixting heater core plumbing and build an air intake for it.
Then your intake air temperature will rise along with your coolant temperature.

A radiator feed for the WAI does have some benefit in the transition. The effect of grill blocking/winter fronts however slows down the air entering the engine bay, That air will get heated up by the exhaust etc.; so if the intake feeds from the bay the temperature does rise more quickly, as was proven in earlier posts.
