Also shikotsumyaku appears to just be a mutated version of all-killing ash bones like two different abilities rather than just shikotsumyaku being all-killing ash bones minus something. All we've seen kaguya do with all-killing ash bones is make and shoot spikes made from bones whereas kimimaro could do a lot more such as ripping out his spine and creating an exoskeleton. No. There's no evidence you require all chakra that BZ assembled to perform All-Killing Ash Bones. At best we can say the missing piece was somewhere in that chakra and physical body that was assembled. We don't know where and we can't say all. None of it included assembling any Hyuuga chakra or DNA either, but there goes that Byakugan. Is her Byakugan a result of ALL the chakra BZ assembled? Clearly, it's just a piece mixed up somewhere in the rest.

Shikotsumyaku was directly related to Kaguya's ability to manipulate weaponize her bones in the 4th Databook. This is not something that I'm making up. The Kaguya clan are related to Kaguya in the same way that the Hyuuga clan are related to Kaguya. They were on the same page in the Databook describing exactly that.
