I can understand that, but I just think show cattle now are so much better from a structure and body standpoint than they were when those bulls were the big thing.
I think you'd have better luck using a breed sire with some power than digging into the vault. There's a fine line between being proven and past it.
Chill Factor was a good bull when we used him, and is line bred to Cunia in a black/white package. He may work to an extent, but monkey mouth, small feet, and bad pasterns are a possibility.
Habanero was immensely popular for a few years, but I would be worried that his daughters could be short on body and again, a little sketchy footed. Maines from this Era were notorious for bad pasterns and it took bulls like Money Man and Ali to really exonerate and legitimize them as a female producing breed again (in my mind).
Carney Man is one of those bulls that wasn't appreciated properly until he was gone. He could work, but he may just be too dated in his make up to really get it done for you.
All of these bulls have merit, even today. But with such a small sample size, I'd go with a really good Simmental or Charolais bull and then follow that with a monopoly son. It's a proven recipe for a reason. It works time and time again, with many applications.
