No, that's consistent. You know how I don't like unjustified exceptions. Brandon Routh's Superman had a bigger role in the crossover than Helena Kyle. When Supergirl and 90's Flash made their cameos in Welcome to Earth-2, we didn't merge them right away. We had even waited two crossovers before Supergirl joined this site. Based on past merges and the context around Crisis, Birds of Prey is not suitable for a merge.
