I can see some logic in this but then again the only books that have had any button Watchman stuff in it have been Batman/Flash/Superman/Action and I doubt those writers will be handling everything that spins out of it, they just are driving the cab whose route is at this particular location. IOW if Willamson was writing Batwoman, I don't think we would be seeing the JSA easter eggs there. Whomever had to honor of writing the titles selected as precursors to the Watchmen Wars gets to play with the Easter eggs.
