That could work.

If you invest 10% of that cost into the aerodynamics, you could get as much in improved miles per gallon.

The topper has beveled edges but it's flat on top. It needs a crown that peaks at 30% of the way back from the front and never exceeds a very specific curve.

But really all the opportunity is in the wheels and underbody. You can reduce lift with a bellypan and it's completely invisible to the people who's opinion matter.
