With the changes brought about by Superman Reborn, Superman's timeline becomes a mess: ten years get inserted after the marriage of Lois and Clark, making it impossible to align events like the Death of Superman with the rest of the DCU. I've been thinking this over for awhile now, and I've come up with two possible solutions to this problem. Each has features that I like. They are:
1. Revert to something very similar to what actually happened before Superman Reborn, with the main difference being that everything from Superman: Lois & Clark to Superman Reborn took place on Earth 52, and that the ending of Superman Reborn resurrected Earth 52's Superman and Lois and sent Earth 0's Superman, Lois, and Jon back home to Earth 0.
What I like about this option is that it's very close to what originally happened; which means that it's the last likely to introduce unintentional complications, the way Superman Reborn did. The downside is that it's fairly convoluted, and leaves some aftereffects to address (e.g., how did the Kents explain their brief absence and the sudden appearance of a nine-year-old son when they got back?).
2. Have the marriage happen out of order. All of the problems that come with putting Jon's childhood directly into the timeline without any time travel shenanigans come from keeping the order of events the same. If, instead, we say that Lois and Clark got married early in Superman's career, and that Jon was already in grade school by the time the Death of Superman happened, all that you really lose are most of the Silver Age and Bronze Age adventures that are based on the Superman/Lois/Clark love triangle. The downside is that it does mean that Lois and Jon Kent need to be retconned into most of Superman's history.
So which option do you prefer: a reversion of sorts to the pre-Reborn events? Or moving the marriage of Lois and Clark out of order and into his early career?
