New idea for a mod (Lions, Tigers, and Bears, Oh My!)

I had an idea for a mod that hopefully someone else can bring to life. Every 20 seconds, the mod chooses from 2 bears, 3 lions, or 5 tigers and spawns them randomly on the map somewhere. It could very quickly get out of hand, and even easy campaigns like William Wallace would become chaotic with this mod. I think it would make for great content and tremendous fun. Unfortunately, I have no idea how to bring it to life. Hopefully, someone else with the time, resources, and skill to do so is interested.

I just realized that the Rabid Wolf might be a better candidate for such a mod, because it’s stronger than ordinary predators and cannot be insta-killed by Magyar villagers, removing that cheese potential.
