I like where the OP is going with this suggestion, but why not buy a seperate area for your guild hall (an area that already exists inside the island)...a reserved section that when finally acquired will spawn an NPC. And that NPC will give you the option to buy enviornment specific creatures that roam your GH in times of peace. (Removed during GvG.)
So you talk to this NPC, and just for a few examples:
Isle of the Dead: You can buy tamed Skeleton Hounds to roam your grounds.
Isle of Weeping Stone: You can buy white tigers and/or rot wallows.
Isle of Meditation: How about regular tigers and/or cranes?
There's a lot of empty spaces while the GH is at peace, so if you could buy a plot of land within your hall to house a creature NPC, it might add a little extra ambiance. It's another gold sink, but a worthy suggestion to consider.
So I agree with the OP to allow animals to roam your halls.
