How would it look if you had masked off all the machined metal surfaces and only painted the as cast part of the wheel? I have 4 turbines with good tires that I am holding on to for just such a trick as yours.
Someone on Four-Eyed Pride has a black hatch with turbines done up exactly like you're describing - looks NIIIIIIIICE.
To me, the wheels in the picture look dirty.
turbines are turbines....ugly duckling
