I've seen a 6 pack scoop mounted to a steel hood on quite a few cars, but it has been a while. you can buy a repop hood and use hinges. You would just need to use a lighter spring so it doesn't bend the hood.
KID
Are you saying the new hoods are that much thinner material necessitating a lighter spring to keep it from bending/warping the new hood? If so, that's an incredibly sad indictment on the repop industry. Are you just 'saying' this or, do you have first-hand information to support this claim? This is important b/c this idea could catch a hold and become a rumor that people believe!
I have a mint 69 RR hood with all the parts needed to convert from a lift off hood. I had a 69 with a lift off hood, I sold the car and still have the parts. I also have a mint trunk and an unused lift off hood. I have other RR parts. Paul (570) 409-8051.Does anyone know where I can find a Road Runner 6 Pack hood that is all steel? Also I don't want a lift off but one I can bolt to the hinges. Thanks in advance for the info.

I haven't checked for your hood but I bought and used a fiberglass hood from these guys for a 72 Mach 1 which was without a doubt the best glass hood I have ever seen or used. I was even able to use factory springs and latch although I did pin the front of the hood for safety's sake.
