I agree, like I said there I think it'd be only done for the sake of copying Superman and Batman. Which isn't the best creative basis imo.
I would have liked to see Rucka's Diana's Daughter have happened though the appeal to me of that was it was out of continuity. Though I guess to lead into another opinion, as much as I was looking forward to that and Historia, I was a bit disappointed the two WW BL projects weren't centered around Diana. There was Dead Earth eventually but that book nuked itself for me in the last two issues.
