This has popped into my mind as well while thinking about things. Aero drag could be significantly reduced without the drag of the cooling system. However, this idea has too many cons to be considered. Here are a few:
1) Cost
2) Lack of avaliable surface area for larger engined vehicles especially when considering A/C
3) Intake air ducts are at the base of the windshield. You wouldn't be able to get cool air through them anymore or they would have to be relocated.
4) Safety
