To opine on your original statement, I would leave the headstock as is and do away with the switch washer.
And to further add to what everyone else is saying, I think the guitar would have to be stained fairly dark for the gold hardware to not seem out of place. the blue doesn't work for me either. Maybe you could save that for a guitar that is painted blue as well. And if it were mine, the back control cover would be stained similar to the mahogany or use black plastic as Drak suggested. All merely my opinion, but when you ask for a toothpick on PG forums, you tend to get a tree limb don't you?
