Lol indeed.  Unfortunately the only experience I have of Damien Wayne was from Injustice, but that said, I know he's not a bad guy for the most part.  In the game he most definitely was since he killed Dick Grayson apparently in the alternate Earth, but this sounds rather interesting to me personally.  My only concern is that we have quite a number of Bats running around as it is, where we only have a couple aliens and metas overall.  That and as far as I know, as it stands now, Dick Grayson stands to inherit everything.
