I see what you guys mean.. Like the Jetta taped front wheel wells, just posted:

When I drew the trailing tail of the crescent, I was thinking about the benefits of the pizza pan wheel cover. How do they help??
Maybe, fast air flow from the front end would bridge the forward gap and flow
mostly unimpeded over the tire and smooth wheel cover, then bridge the gap on the trailing end of the tire and onto the door.
If a large gap exists, fast air over the tire will
pull air out of the wheel well and increase the turbulence across the door and down the whole side of the car. That gap could be the point where a big separation of flow occurs..

If the upside down crescent was really close to the tire, with a really small gap, with a moon disc installed, how much different would that be from a full skirt??
