Just curious, but could you not remove the piece from the car, take it to a custom metal fabrication shop and have them replicate it exactly how you wanted it? Even in the exact type of metal quality and finish? I have a friend who works for a metal fab shop here in Jax, and I believe they do stuff like that; one or 2 off pieces, without needing a minimum 20, 50 or 100 piece order like you might think.
Make a few calls around to some local metal fab shops in your area and see what they say. Maybe you could come up with something more unique than anyone else and exactly how you envision it being perfect to your own taste.
