So Obito's chakra/soul came from his ashes, so couldn't Kakashi carry a gourd of his ashes like Gaara and have access to Obito's sharingan whenever he needed? Obito said he could only temporally "possess" Kakashi but he didn't say he couldn't do it again. Rin said she was able to watch over Obito this whole time she was dead so i guess Obito could watch over Kakashi to see when he needs the sharingan.

(If of course Kakashi could recover Obito's ashes in Kaguya's Dimension)
