Duster meets Challenger hood, thoughts please?

I have a 73' Duster that I just started doing a full custom, pro touring build on and have never cared for the factory hoods bulge / hood lines of the later Dusters. I have considered the fiberglass cowl hoods offered, but at the expense of having my car called a Nova would rather not use this style. A six pac hood would be a good option as well but I would like to find something more aerodynamic. For this car, I would really like to do something a little different. In my searching I found this Duster / Challenger hood picture online and am somewhat interested in doing something like this to my car minus the weird shape in the front.

I am assuming they probably just got both hoods and welded / grafted them together, has anyone ever seen something like this done? Thoughts or other ideas would be appreciated?

Thanks,
73 408 Duster
