Marvel and DC

What if the Marvel and DC were always one universe what kind of stories would result? What if sometime after becoming Oracle, Barbra Gordon becomes a horny She-Hulk? What if Harley Quinn gains the power to dominate minds and make whomever she wants hers. What if Natasha Romanov became a fat hedonistic crime lord that seeks to fulfill every perverse pleasure and desire she has. What if Susan Storm was infected with Joker's infected TITAN blood? What if Supergirl became a self-obsessed attention seeking bimbo of a celebrity?

Now then What If?
