While it's true that some sort of compatibility helps with becoming a tailed beasts' jinchūriki (Gaara being the only one out of the Fourth Kazekage's children compatible with Shukaku, Fukai and his uncle and father being chosen as Gyūki's jinchūriki before Killer B, Kushina being chosen as Mito's successor as Kurama's jinchūriki because of her special chakra), nothing says that one can't become a jinchūriki without meeting some requirements (apart from the Ten-Tails having to be sealed in a living and not reincarnated body), though I agree that some factors definitely help in controlling the beast's power (having the Sage's body or eyes).
