In a perfect world, in like 90% of DC comics Superman and Batman's relationship would remain the same.
The other 10% should include the following:
At least 2 typical universes where they are a romantic pair.
At least 1 typical universe where they are in a romantic polycule with Lois.
At least 1 typical universe where they are in a QPR with Wonder Woman.
1 universe where they are evil and in a healthy romantic relationship. ('I hate everything except you' situation)
1 universe where they are evil and in a toxic romantic relationship. (maximum angst required)
And at least 3 typical universes where they are canonically in a QPR.
Note: At least one of the evil universes should be the Justice Lords universe. And one of the typical romantic universes should be the Justice League Animated Series universe.
