Brake Ducts In Steel Apron?

is anyone running brake ducts in the factory steel apron? My car is almost ready for paint, so I'm trying to get any last body mods done before then.

I live in WA, and we have to run a front plate here, no way around it. I originally wanted to use a street apron, but there is no way to make a license plate look good on it.

I was thinking of putting in oval shaped brake duct holes just inboard of the vertical bumper guards. Has anyone done this? Do you have pics? I just want to make sure it doesn't look terrible before I start cutting.

Unless the apron is dead flat where you want to put the holes, i'd be worried about the punch warping the metal.
