The topic has taken an interesting turn, and there's some interesting information to consider. I decided to think about which creatures might be better suited to different factions. Dwarves would probably be better in the Dungeon – they are miners, after all. Harpies would be better in the Stronghold – it's inconvenient for them to fly in the Dungeon. Fairies belong in the Rampart – they are forest dwellers. Centaurs might also be good in the Stronghold, but I'm not sure. The other monsters, in my opinion, fit quite well into their respective factions. Therefore, I can't say who should replace the ones that are moved.
