I've read about that before. At the same time, just because the creator had an idea for a long running character doesn't mean it was a good idea.
See, e.g., George Lucas and the prequels.
He wasn't a long-running character when they considered doing it...he was only a couple of years old. Had they gone that route, Lois knowing Supes's identity would likely have gone on to become a traditional aspect of the mythos in the decades to follow...like the Daily Planet, Perry White, Jimmy Olsen, bald Luthor, and Kryptonite, all of which were either just being established around 1940 or yet to come.
The Star Wars prequel example doesn't apply it all. It's more akin to deciding that Vader would be Luke's father while making TESB.
