With editorial seemingly set on their path of killing off new52 Superman and substituting SuperDad for him on his titles come Rebirth, at least for the moment, I was thinking about what could be done that would both give new52 Superman fans a chance to read a book about his continuing adventures in real time, and not mess with editorial's plans to have him be presumed dead in the main universe.
What I stumbled upon is this: What if new52 Superman is, say, seemingly vaporized in a heroic act of sacrifice by getting between the villain Superman's solar flare and the other members of the "Super League"? It would kind of fit with the cover (or at least the artwork they have solicited in some places as the cover) of Superman #52. And of course, everyone would assume he was dead. So, they could carry on exactly as they plan to do with the post-Rebirth titles.
*However*, what if instead of being vaporized, in reality, Superman is unmoored from his home universe, doomed to travel from parallel world to parallel world on a random basis, never knowing when he'd flash and move to the next world? You could do a new monthly about his adventures in a bunch of parallel worlds, both ones similar to the real world, but with alternate histories creating divergent presents (i.e. What if the Russians won the Cold War?) and radically different ones where the sentient life on earth is essentially alien because of different evolutionary paths. All kinds of interesting opportunities there. Maybe he could even end up in SuperDad's old universe for an issue or two, where SuperDad and Lois are missing and presumed dead.
That'd be a fun book, I think, and it would still leave him "dead" in the main DC Universe and unable to pop up in stories, while potentially allowing them to bring him back if they want to (i.e. He might randomly flash back into the universe and find someone who could anchor him there before he randomly pops out).
The book would have to deal with him seemingly having a deadly disease that is killing him anyway, but the answer to that could be as simple as the same flare that led to his apparent death in the main universe and is moving him through other universes recharged and cured him or that he found some high tech earth, or a still living version of Krypton, in his random jumping from universe to universe, and was able to get fixed up my medicine beyond the current abilities of anyone in the main DC universe
Thoughts?
I'd definitely subscribe to a book like that.
