grillblock in front, not against grill ?

has anyone ever tried an external grillblock that sits in front of the grill rather than against it?
the idea is that i'd install a lip (a found a very nice piece of plastic that's just right) in front of the open area of my lower 'grill', basically turning the intake from faceing forward to faceing downwards

the red area is the dam i plan to install


the basic thought behind this is that it might cancel out the ram effect somewhat reducing the air intake at speed, but allow a maximum volume of air to enter naturally or be sucked in by the fan when the car is moving slowly and most at risk of overheating.

i plan to try this but does it look like it might work or should i look for a different approach?
