Temperature controlled grille block

With grille blocks, the more you cover up, the better the aerodynamics of the front of the car, but also the greater the risk of overheating the engine compatment. A totally covered grille is good while the engine is cold, since it helps it warm up faster.

How about a grille block which slides open when the engine gets too hot? It would be a sliding door type affair, maybe it could be manually controlled by the driver with a lever or a button, or automatically opened and closed through a temperature sensor. If the optimal temperature of the engine coolant is 85 deg.C and the fan kicks in at 95C, then have the grille block slide open at 90C. Or maybe open partially at 90C and all the way at 95C.

It's hard for me to believe that I'm the first one to think of this, but I couldn't find a relevant post. So has anyone already discussed this? Any comments?
