You just inadvertently gave us a way that Kaido can be taken out of the equation without him being killed. If Kaido gets OKoed and Law hacks him to pieces and they scatter his body all over the New World, then the threat of Kaido exists no more. In fact, we did see something similar to this pre timeskip, and Oda loves to parallel events of preskip.
