So, random realization.
...Kabuto's ability to generate snakes is probably related to his DNA technique, which is derived from the combination of Jugo and Sakkon's bloodlines...
But I ony just realized how similar that is in nature to the Ten-Tails clones.
So there's more canon evidence for my theory about combining bloodlines/traits to add up to Ten-Tails Physiology. Kabuto said that his chakra was highly similar to the sage of Six paths but that's probably becuase his body was as close as you could get to Kaguya without being an Otsutsuki or Ten-Tails Jinchuriki. (Er, I mean, Hashirama cells probably would have gotten him closer but he was planning to do that next.)
