Superman has nowhere near the necessary style to pull that off. He'd manage to somehow put himself in the path of some contrived kryptonite ray no matter what, and then Batman would have to bail his pansy ass out.
Batman and Superman will never happen due to greed. It be interesting to see if they actually made a real Justice League movie though with Batman, Superman, Wonder Woman, etc. Batman kicks Superman butt because sups a bitch, otherwise Batman would die instantly. I'm just taking into account how much power was given to him, you take away his I'll never hurt a fly nature and all you get is ashes left of Bruce.
