A question arose as to which were the originals and which were the copies; this question was ultimately answered by the Time Trapper, who revealed that he had bifurcated the timeline, and both were the originals — in their respective timelines.
Of course, that revelation took place during the Legion's Zero Hour tie-in; and shortly thereafter, we got the first Legion reboot.
I could see the current Superman dilemma resolved in a similar way, with Dr. Manhattan taking on the role of the Time Trapper: with Superman, DM didn't merely “steal some time”; he split Superman's timeline, resulting in two versions of Superman coexisting.
Or maybe instead of a time-split, a solution could come in the form of a time-loop: sometime over the next two years, Superwoman and Clark Kent (from the current Action Comics, assuming he's revealed to be a depowered N52 Superman) pair up and she ends up transferring her powers over to him, restoring his status as Superman and reverting her to Superman's girlfriend, Lois Lane. They get married, and Lois becomes pregnant; then, shortly after their son's birth, something happens and they're thrown back in time, arriving in the past the day before the JL forms with swiss cheese memories. Thinking that they're refugees from another world, they decide to settle down in secret and to work from behind the scenes…
In other words, explain the two Supermen by saying that Superdad is Nuperman's future self transplanted back in time.
