That's sort of what Im thinking. What sort of weird,
new stories could you tell with a Superman who is not a native of the universe?
Everyone was de-aged in the New52, including Perry. Now Perry isn't that much older than Superdad (certainly older but not like it was). If DC has some balls and doesnt retcon out the last few years or fold Superdad into the history, what would the interactions be like between Clark and Perry now? I can actually see them becoming close friends, with none of the "mentor/student" dynamics they used to have, and that's interesting. You dont even have to have Clark working at the Planet for this to happen, you just have to have them meet each other.
What would happen if Superdad travels back in time and meets the Kents of the 52 before they died? That'd be such a f**ked up, heart-breaking story no matter how you play it. Does Superdad tell them the truth? Does he play along to save them pain? How does that affect him?
We're seeing how the League deals with this new Superman and I gotta admit, I like how unsure they are. Yeah, the guy's a Superman. That's obvious. He's trustworthy enough to call him in when giant space monsters are eating the planet. But they're very concerned and I dare say afraid, and that's a really fun twist. Obviously it wont last and they'll build relationships and trust of their own, but the fact that Superdad isn't the guy they knew is going to impact that going forward. Especially with Diana.
Its a rare thing but if DC holds its course (which I am certain they wont do) we could actually get a (somewhat) brand new Superman construct. Imagine that. Something new, after 80 years. How is that not worth exploring? Seems more fun to me than the same old status quo (much as I love that status quo and consider aspects of it critical to the character)
And if nothing else it could tackle and solve some of the fundamental issues that Myskin likes to bring up.
