They look good! I see since you're rockin a white grille like myself, I would be partial to painting them as well... and possibly leave the very bottom "extended lip" part of them in CF
I've used the body-color-paint-in-an-aerosol-can before, and have to admit it matched the OEM paint spot on. For like $25, you can't beat it!
Once painted like that, what if you bought some green pinstriping vinyl, and laid a 1/4" x 8" stripe in the middle of the exposed CF then, leaving a CF border around a thin green accent line on each one? I think it might bring the wheels together, sort of like the green mirrors before.
