[DC] What would happen if Superman killed Batman?

Batman is always prepared for everything. He probably always carries Kryptonite around, just in case Superman goes rogue. Most "Superman vs. Batman" fights then devolve to "Well, then Superman could just one-shot Batman with heat vision from orbit without giving Batman any time to think or react." Since this is one of the most commonly-raised responses in such discussions, clearly Batman must be prepared for the possibility that Superman would go rogue without warning and kill him without any chance of reaction.

So... what is Batman's contingency plan, should Superman unexpectedly turn murderous and kill Batman?

We here at Wayne Enterprises would like to announce our latest project, a joint venture with Queen Industries, our revolutionary new K-Power. Using the various deposits of natural Kryptonite that have landed on the planet, as well as synthetic Kryptonite we have created a nearly endless clean energy source that only creates minimal amounts of waste Kryptonite dust that can easily be ejected into the atmosphere. This K-dust has no foreseeable effect on any life form from Earth.

After our leader Bruce Wayne went missing, it was revealed that the last project that he was working on was this, a gift to all of humanity to save us. We have put into motion a plan to hookup plants on all continents and a revolutionary North Pole Wayne Enterprises research facility that will be powered for eternity with clean, efficient K-Power.
