Why does it matter that those books were published before Zero Hour, Hypertime, 52, Flashpoint and Convergence? Those events have absolutely nothing to do with the Earth-2 to Earth-1 transition, which occurred in the 50s.

Now that I think about it, Earth-1 Batman's first appearance can't possibly be Detective Comics #327 (as given in Who's Who: The Definitive Directory of the DC Universe #2) since that's well after the formation of the Justice League.

The DC Heroes books might still be our best resource for dealing with this issue.
