I think the problem here us getting the more zealous parts of Beacon to agree to a cease fire too. That's the problem of being in a large organization, and Alicia certainly can't guarantee that someone wouldn't act of their own initiative. 

Now if the monsters/dark magical girls/horrors were willing to maintain good behavior amongst themselves by force there might be some place to go, but somehow I doubt anyone is going to agree to that.

I suppose that is true. For this alliance to realistically work it'd need to somehow make it above to all the major leading factions and all of them agree to policing themselves, regardless of the circumstances.
