Fiberglass hood mods... crazy?

bill;this is just a thut: what if you take a piece of sheet metal and go from the front bumper back as far as you can go and fasten it with screws to the frame. then up on the cowl cut 1 1/2x3in. oblong holes maybe 3 and let that little bit of air vent threw the cowl vents that's already there.in front of the windshield and this i know for a fact that by putting a front spoiler on the front like the ones they sell for the dusters&darts is worth 8to10 mph.just been thinking about this scene i seen this thread the other day.
