There's something I've been trying to make sense of regarding Naruto's jinchuriki powers.

Before his duel with Kurama, Naruto could use Version 1 and 2, and when Kurama took over during his fight against Pain he started turning into a flesh-and-blood replica of it. After his duel with Kurama, he gets suddenly Nine-Tails Chakra Mode and his Tailed Beast Mode is translucent and made of yellow chakra. Why didn't he just get full control over Version 1 and 2 and transform into a flesh-and-blood biju like Killer B and the Edo Tensei Jinchuriki?

(I know he can still use Version 1, but then the question becomes how exactly is Nine-Tails Chakra Mode different from Version 1, and why use one and not the other.)
