Not sure about the idea of Kaido being a dragon DF user. I think his devil fruit ability would be a mythical zoan with a multi animal coponet to it. Either a chimera ability allowing him to combined multiple zoan based abilities, or a hydra ability that would allow him to generate an almost limitless amount of heads while in his hydra form.

A more unlikely idea is that he has an ability to control zoan users. Kind of like a pied piper or animal tamer of some kind, but I think it's unlikely.

To me it feels like his ability should have some play on the fact that he gather all kinds of zoan users.
