roleplaying a zombie, nice idea but I don';t think it would be much fun if every post the dialogue would be the few variations of mumbeling the word BRAIN (or Brian if you're trying to be funny) but Zombieroleplays aren't my thing, post apocalyptic isn't either, but you can give it a try since there is a large amount of people interested in them.
the guild war idea seems a bit unreachable, the illegal guilds can wage war in the shadows but actual open warfare and combat in the streets between fightersguild and magesguild... just doesn't make much sese, however there can be a Fightersguild Vs Blackwood Company roleplay with a few fights away from the cityguard in caves, forts or just in the middle of nowhere.

Well, one way you could have a guild "war" would be two legal guilds usinng politics and subterfuge to try to make the other guild illegal.
