That's a really late response considering that I made the Earth-Crossover page a year ago, and it's still there. the talk page ended with me. We have pages for Superman and Batman. Also should we really believe that Marvel characters share the same Earth as DC when there are comics where they actually travel to the other universe? Marvel assigned a reality number to those crossovers, and I don't think DC characters were familiar with the Earth-616 characters, despite meeting the Earth-7642. If there are crossovers that imply that Marvel and DC share the same universe and other crossovers where they actually go to the other universe, then there must be an Earth that those two companies share the same universe and Marvel identified it as Earth-7642 in the MDP:Official Handbook of the Marvel Universe A-Z Vol 1 3.
