No, here you will not get clowned on for asking relevant questions, nor for tossing up ideas. If they were already discussed, you will either get an answer or a link pointing to the thread.
Even if you come to EM with snake oil or other charlatan-esque wonders, then we first ask for hard data, as we are open to new ideas. Only then we will try to explain why your proposal may not perform as advertised.
Only if you turn out to be less open than we are, and do not provide hard data nor listen to explanations, you might end up being the newest clown in the Unicorn Corral.

Regarding channeling air from the front to back, as Freebeard mentioned this seems to work when the distance is short and the cross-section large. In this form you can already find some examples in productions cars.
The longer the "tunnel", the more bends and kinks in it, the smaller its cross-section, and/or less circular it is, then the more internal drag it will have. At some point it will hardly be moving air and its benefits will be outweighed by the system's weight, cost or complexity.

Unless you can bore a large hole down the middle of your car, you will be better off with blocking those small holes and pushing the air to the side or top of the car, where the airflow is (hopefully) already smooth.
