If you're not shy about playing with silicone and fiberglass mat, set some pennies aside and check out both smooth-on and US composites for molding your own. I'm contemplating doing the cladding, just haven't had time to pull the mixer and vacuum bagger out and get sticky

You could quite easily mold in whatever sweet one-off hood insert (vent, cowl, etc) you wanted! Yeah, it'll cost a few dollars, but if you make a three and sell two, recuperation of costs wouldn't be hard to achieve
