The problem with the scoop is that it would not be so small.

There are 27 louvers on each fender (at least on my 66 fenders).  The
average height of the louvers is 4.4 inches.  They are 0.28 inches wide. 
This works out to 1.2 in2 per louver.  Knock 10% for the radii in the
corners and you are at about 1.0 in2 per louver.  Total open area for
cooling per fender is therefore 27 square inches.  To get a scoop that fits
over the louvers (there were aftermarket ones out there at one time) you
would need a scoop that is 5 inches tall by 5.5 inches deep. You could argue
about making it a little smaller if you rely on a ram air effect, but this
is not true at idle.

The scoop would also add to the drag of the car by increasing the frontal
area and adding another bump to disrupt air flow and add to the turbulence
(and thus drag) behind the car.
