Actually? There's a digital-first comic Adventures of Superman that does basically that. It's a series of short stories, usually one issue a piece by a different creative team each time. So far, there's one collected edition of it, which I greatly enjoyed. First time I've been able to enjoy new Superman stories for a good long while.Now all we need is a Superman story based in a pre-New 52 universe and order will be restored.
But of course, because we can't have nice things, it's already planned for cancellation.
