As doc mentioned on another thread, the idea of Batmen setting up a league of Batman that nobody knows about, in order to further the whole "unkillable urban legend" thing sort of makes sense.

Turning Batman into a public corporation doesn't.

Yeah, in the grand scheme of a Batman that's had various ill-thought out stories told over about him over the past 70 years one can always cherry pick something that supports why this particular bad idea builds on the past.

However, just because a story can be told doesn't mean it should be told.
