Zombie survival in Antistasi Ultimate?

Hello guys, I'm relatively new to Antistasi (only played 2 sessions with ACE and RHS so far) and I was wondering if it's even possible to implement a zombie survival system, where we need to loot for supplies (like food and water). I'm also wondering if it's possible possible for WebKnights zombies to be more aggressive towards other factions, or possibly even act as a faction themselves?
