Front skirt idea

I have an idea for a front wheel skirt that would likely work really well.

Build a skirt that fits in the fender opening exactly. Hang the bracing for the skirt from a pivot at the top of the fender opening so the skirt is able to mimic the turning motions of the wheel. Build a swing arm on the frame of the skirt which would link to the steering mechanism so that the skirt will steer like the wheel, and effectively stay out of the way. On the inside of the skirt build a semispherical extension that will keep the skirt shielded from high speed air for the common degrees of turning; it wouldn't be necessary for the extremes of turning necessary for parking, only for the 10 to 15 degrees needed for driving.

What I'm imagining is somewhat like the front fenders that were mounted to the plymouth prowler, which are really mounted to the suspension, but have it modified to be able to work inside of the fender, and of course adding the skirts.
