We know that he unconsciously began locking away his power after he fought Unohana so that he could draw out and enjoy fights. Yachiru might've been created by Zaraki or even his Zanpakuto to contain that power, which is why she seemingly disappeared when Zaraki awakened his full strength. Sure why not that makes perfect sense in every single way
