Heat soak - vented hood options that are not "louvered"

Some NACA ducts like the gtr would work if we knew where to put them. I'm not convinced any of the aftermarket hood makers have done any more testing beyond

With the way the Z is shaped, I don't know if NACA ducts on the hood would actually pull air in or whether air would just flow right over them.

I was warned by several people not to modify the stock hood because it "wasn't safe" but I'm not sure why that would be short of possible (?) hood latch issues.

Would it be possible to have a custom scoop like the one pictured above fabricated and attached and a hole cut into the hood by a really good body shop?

From my testing and experience on mine, as far forward as possible! I don't know how the gtr works being so far back but I don't think they're a heat thing. I think they're a stabilizer or something because if you watch the making of the gtr on youtube they're insane with aerodynamics and drag etc etc.
