we know Naruto can Transmogrify chakra so that others can use it namely the chakra of kurama. but there is no reason to believe he couldn't do that with other chakra like the uzumaki chakra in his body or the chakra of asura thats in his body etc etc
so Naruto could Transmogrify the six paths senjutsu and give it to kakashi that way kakashi would still be capable of fighting with them in fact more so then he use to be being that the six paths senjutsu is is more powerful then any normal sharingan also having sage mode would allow him to use raikiri and chidori also grant him incredible strength
