I think it might help for the Super-books to have a "head writer," who oversees any other writers working with the character, like a TV showrunner, so you get a whole bunch of harmonious ideas developed in concert, rather than here and there. But most of the time when that happens, it's a strong editor -- Mort Weisinger, Julie Schwartz & Nelson Bridwell, Mike Carlin -- rather than a writer.
But, well, who knows?
