Warmer air

My vehicle is the old style speed/density system, and on cold days or early mornings my exhaust manifolds, where my intake air comes from, gets hot before my engine is closed loop. This causes some issues with running way way rich from about 2 minutes after start up until about 10 or 12 minutes of drive time. So I'm building a dual intake air cleaner with some flex vents that I can switch from warm air to normal driving and cold air, maybe ram air, for heavy towing duties.
What about ducting the intake air to the radiator? It would warm up right after my block gets hot taking care of my temp rich condition, and reduce the need to use my electric cooling fan and maybe cut out some drag on the alternator. thoughts?
