one fault with this theory is the fact that when starkk and lilynette were still one being (pre diffusion), they looked different from what either of them look like now, meaning that if yachiru were to have been part of him, kenpachi would: know that she is part of him (which means that he wouldn't be surprised about why/how she disappeared, as both starkk and lily knew who and what they were, and how to go back and forth from their fused, and unfused states); it would make no sense for her to know about his shikai and bankai, since kenpachi himself doenst (if she were to be him, they would have the same amount of info and knowledge as the other would), and her having a different a shikai is tough to deal with, since we know that zanpakuto spirits have used unknown zanpakuto powers before, that the owner had no idea about (fire abilities on komamura's i think, bankai lvl abilities being used in shikai state on hitsugaya's case, and i think a few more as well)
