It wouldn't make sense with the official lore if he were to do that. The fat Majin Buu we know was caused by Super Buu absorbing the Supreme Kai, who lobotomized himself before being observed. This effectively reduced Buu to an infantile state, creating the happy stupid persona we're originally introduced to. The natural form of Buu is Kid Buu, and it's likely that anything of the same species would have a similar shape, or a completely different one based on what that Buu had absorbed.

Thats why you call Kid Buu a mutant. My explanation is to make DB Xenoverse make sense, which is something Toryiama really wants to bring into the actual lore.

I mean, Toryiama did the same thing and called Freeza and his family a mutant to make that race work in Xenoverse.
