This thread here contains all the hints that may support the theory of Yachiru being Kenpachi's Zanpakutou spirit: https://www.reddit.com/r/bleach/comments/2te6bc/yachiru_is_nozarashi_and_kenpachi_might_go_bankai/ Also, Yachiru might have gained an actual body due to Zaraki stealing the Asauchi from the corpse of a Shinigami, who had most likely started to pour his Reiryoku into it. What if Zaraki's problems with his Zanpakutou originated here? I'd add that Yachiru is immune to Kenpachi's Reiatsu, which is only natural, if you assume she is a manifestation of his sword, but nearly impossible if we consider her just a normal girl.
