I was wondering if an opening that small could be a source of drag due to the high pressure entrance of the relative wind. Could the "tear drop" flaps (as per the drawing) provide a significant decrease of such drag ?

I like the sketch. I think the idea is to divert as much air around the car as possible so the small opening is a good thing. The AeroCivic and AeroHead's T100 have very small manually adjustable grill openings. IIRC I read on here that the opening only needs to be 1/5th the area of the radiator if it is ducted, which it appears to be in your sketch. IMHO if the adjustable blockers are teardrop shaped I don't think you have to worry about drag behind your grill opening. All cars sold in cold climates should come with automatic grill blocks.
