Don't know if it's "acceptable", but that's what I wanted to do to my 1960 GMC for about 20 years - install a 1960 Chevy hood. Sadly I never found an example in good condition at a price I could afford. What I like about the 1960 Chevy design is it's the style the entire series of trucks was designed with in the beginning, and in my opinion is the best looking of them all.
More recently, I've been playing around with a custom hood design which I would like even better, combining the upper panels of the early and late style. If I can complete a version in 1/25 scale I'll post photos for opinions.
