67 Barracuda Hood louvers - but actually real

I am contemplating having a shop 3D scan my existing hood inserts, and reproduce them as functional hood vents. Currently in a restomod of my 67 fastback and am trying to build the car the designer envisioned before the accountants got hold of it.

Anyone done this before? Already worked out how to reinforce the hood for the holes to be cut, but would be interested in seeing other design ideas.
