I took the car for a good drive and didn't hear any contact on the skirt. I also used the jack to compress the suspension up into the wheel well, and still no contact. My main concern about the gap is actually for ice and snow build-up. I'll report back after I drive on snowy roads.

As for the front fenders, the easiest thing would be gap fillers along the front & top, and a large radius transition on the rear portion of the arch.
