Literally just spent an hour playing sword with my little girl (<5): “You be Lex Luthor, and I’ll be Katana!” (I talked her into letting me be Deathstroke, who actually uses swords.)
I know everyone is focused on Blade because of the celebrity attached, but I think Disney will find that fumbling Moon Girl will turn out to be an equally careless move that leaves money on the table in the long run.
