wiper cowl vent delete

now this might be a little out there..... :wack:

has anyone covered the slotted vents in the wiper cowl?
I know If I'm running A/C that I would have to get clean air from somewhere to be able to use the vent setting (maybe where it drains into the fender, run a tube from there to the front of the car or just let it suck from the drain openings)

Does it look strange? it should allieviate the leaves plugging the drain holes(not that the car would be parked out in the elements, but)
Just thinnking out loud.. :scratch:
