It would only fuck up the histories of the Batman Family and GLC. Which doesn't make much difference in the former's case, since none of their histories make sense anymore right now. But I'm not talking about the characters, I'm talking about their stupid earth-designations. It's only a matter of time before someone in Worlds' Finest or Earth-2 starts calling it Prime Earth.

Strikes me that the wikipedia method with the out-of-universe publication histories would be more work, and have less information.
