UH....... NOOOOOO.
I'm sorry, but your information is incorrect. This was the very FIRST thread that I ever wrote, what if Minato sealed the other half (YIN) of Kuubi chakra inside himself...? The greatest Hokage ever is what I called him...
...until someone brought me back to reality. Minato originally sealed half of the 9 Tails chakra INSIDE THE DEATH GOD not inside himself. He then sealed his own sould inside the Death God. Same way 3rd Hokage sealed Orochimaru's arms inside the Death God, NOT HIMSELF. He still had markings on his body but this does NOT mean he sealed the 1st and 2nd Hokage and Orochimaru arms inside of himself lol it was in the Death God dude.
Secondly, You cannot be a Jinchurriki with ONLY A SOUL. And Minato's SOUL was sealed in the death god, not BODY. So it is impossible for Minato's soul to seal the 9 Tails inside... you need a physical BODY for this. And if he was brought back Edo... the other 9 Tails would also have to be brought back edo... and hell if I know if an edo can make himself a Jinchurriki. Too much for my brain dude, impossible.
