Since the Shinigami was cut open does the Yang chakra sealed by Minato disperse back to the Kyuubi? I believe it could because Oro's arms came straight back to him and if it did Naruto would get the power boost to challenge the 10 tails. What do you guys think?
2 things about that. All people that use the seal get the seal mark on their belly. Remember that Hiruzen had the mark when he sealed the senju bros. They weren't actually sealed inside Hiruzen.
Also, edos can't be jins. If Minato had the yin half of Kurama's chakra then he'd be a jin.
