WARNING: Spoilers for the Planet of the Apes reboot

Since Apes and Zombies are all the talk recently, I have an idea for a crossover: Planet of the Apes / The Walking Dead.

What if the Simian Flu affected humans the same way that the zombie virus does? So instead of just getting sick and dropping dead a few days later, the contagious virus spread throughout the world, causing dead humans to become walkers while making the primates intelligence.

Does anyone think it would be cool to see Caesar and his ape army fighting against a city full of walkers?

And which do you think is worst: an ape apocalypse or a zombie apocalypse?
