Uhhh...the whole "guardian of Hell" thing with Yamamoto was simply Kubo describing his demeanor and powers in a dramatic way. He isn't actually the guardian of Hell, there isn't any will to inherit like the Will of the D in One Piece, and the name would likely include Jigoku (Hell) in the name. Instead, it appears to have Dangai (Parsing World) in its name.

tl;dr highly doubting it.
