Something I have been thinking about: What if you shaped proper all the wheel skirts to essentially "replace" the need for smooth wheel covers?

The reason I'm considering this idea: I have aluminum wheels that are very light weight (Rota Slipstreams) but FAR from aerodynamic. Doing smooth wheel covers would likely require drilling/screwing into the aluminum spokes, which isn't something I want to do. Instead, doing all 4 wheels skirts that would extend in the middle low enough to cover the wheel.

One benefit to this that I can easily see, though miniscule, is reduced rotational mass. 4 "pizza pans" and some screws adds up to something. There is also wheel balancing to consider as part of that equation.

Any thoughts on the matter?
