We all saw that there are currently TWO Kuramas.
They are essentially 2 "different" beings made from Kurama, just like the Bijuus are 9 different beings made from the Ten Tails.
So, if Minato really passes his Kurama to Naruto, will Naruto's Kurama absorb it or he'll become host for two tailed beasts???
BEING ALONE IS BETTER THAN BEING WITH A WRONG PERSON.
Re: Naruto become a double jinchuuriki????
The nine Bijuus were made out from the Juubi's chakra. They are purely chakra forms. The only thing they possess the body and bones is because they were imagined and fed chakra by the So6P. The chakra can be divided and used in various forms like earth jutsu, water jutsu, fire jutsu by the same user (same chakra).
I believe that Uzumakis had a skill to use imagination powers to their seals. For example, Kushina's chakra chains, The jail Kurama was caged inside Naruto along with a lock, They were all solid in chakra forms. Even the gates of God which were slammed on Kyuubi and caged him again by Naruto. Similarly, Kurama was divided by the Uzumaki seals, he must have got the same characterization as that of the original Kurama inside Naruto. This is just a thought that came in my mind while posting.
Most likely they will fuse into one personality, but I think it would be cool if they kept their personalities... kind of like how Naruto wishes to save the Bijuu, Naruto wouldn't want to destroy both Kurama's by fusing them.
