Once again the gains are at the rear. I don't know why mirrors would be any different than any other body being pushed through the wind- except that they are usually located in an accelerated air flow zone from the greenhouse. Anyway if an object is too blunt for the air flow's liking, the air takes care of it itself by forming a largely stagnant bubble. Thus I wouldn't predict any sizable gains, if anything at all, from elongating or rounding the front of the mirror housing. We know how awful the flow can be coming off the rear though- it's a major source of wind noise.
