Then I guess your only alternative is to go to a custom fabricator like I did, and just tell them what you want, and have them draw something up for you.
The shop that built my hood did it exactly the way I wanted it done. It came out looking better than I had ever imagined thanks to their incredible skills and workmanship.
I don't know where you're located, but you could go to some car shows and check out some "custom" cars, then ask their owners who did their work. That way you might find someone to build you a hood.
