Nice to see another monaco!
I know what you mean about the gold but not sure they'd look so great in the flesh against the real colour of the Monaco. Since its a bit more purpley in light, it might look quite odd. Unless you can put a William's gold wheel against it first to see, I'd be very hesitant to get them done.
I'm considering if to paint the wheels as well but I think anthracite looks like what they look like now: silver covered with brake dust lol But if the car and wheels are nice and clean, will look spot on.
