1. A grounded/street-level book about a black clone of Superman who has all of Superman's powers, but not at the same levels (see: leap tall buildings, but not necessarily fly).
2. Start a digital-first line featuring fan-favorite characters (see: Donna Troy) in new adventures that will only be printed in trades. Digital release of single issues and then hardcover/trade (same day) release. Figure it'd be an interesting experiment, if nothing else.
3. Look for more "rising" talent rather than "established" talent.
I'll agree that there's entirely too much "go back" and fixations on certain characters, but it's fan-booking. [shrugs] People gonna play favorites.
