I like the third idea, but for one reason i don't think it will happen: Oda is not redundant. There is already a being called Cerberus in the series. While it is a zombie and not a devil fruit user, the theme is used. Same goes with any hydra, wolf or tiger devil fruit - they are all to similar to existing abilities. Oda isn't known for recycling his ideas, one of the reasons why one piece is so popular - there is always something new and mindblowing coming our way.

But even if i think the cerberus df is garbage, your idea of Blackbeard having a split personality is super awesome - love it and it fits his behaviour
