Don't forget Batman's new sidekick!
Why stop there?! Bring in the Punisher, so that he and Moon Bat can exchange tactics:
Yeah, I don't think they'll go for a straightforward approach to Red Hood.
My guess is they'll play it like Se7en. Where instead of a "John Doe" killing people in Gotham, there's a "Red Hood" doing that. Then you learn when Jason's not in his Robin duds, he's wearing the red hood.
In summary, you merge Red Hood with Robin.
Its ****ing tragic and would perfectly explain why Snyder told Affleck than by the start of BvS, Batman has been morally bankrupt for a decade.
The purist in me says "**** no", but the fan-boy who just wants to see new, cool stories says "**** yes"... Just don't let Snyder anywhere near it...
