what most gars with good aero seem to be doing is have the airdam lower in front of the tires and more sharply cut, and higer and smoother in the center to allow the air under,

perhaps you could cut down the sides a bit and fold back the center section below the bumper to form the undertray...
a coastdown test might hint at how well things work
