Not quite sure about the artic silver but Thule's silver colored boxes match Titan Silver almost spot on.

I'm certain that if I were to shove the box to one side I could get one or more bike racks on it.

As far as airflow and all that-it does protrude over the windshield in order to open the rear hatch. I find that the noise goes down with the box on vs just having the xbars on. On paper there is probably an ideal placement for the box front to back-but in reality your really not going to notice any significant drop in mpg. Your sticking a box on top of a box. Couple that with the fact that you have probably loaded everything pretty much to the max, who cares where those few tenths of a gallon went?
