The Pillow Palace? Girado is most delighted, he needed something to work as cushion for his experiments with catapults, see.

I don't see much reason to bring us up to thirteen, as wouldn't defeating superior numbers be better proof that they're the dominant force? Numbers aside, as long as the Cero remains dead in a ditch, I can at least see it working out and we technically had 11 in the first place if you count the Exequias (And, perhaps Espada 11 should have that as a special duty or something?).
