Shouldn't he need some uchiha dna? I mean lets say he wants to use susanoo, kakashi had done that when the chakra of obito was infused in him, there is that thing tobirama said about some special chakra the uchihas awake when the unlock the MS, I think the only evidence for this is the last film where kakashi look at the piece of moon and can't do nothing, but sasuke put up the susanoo and cut it, so I'll assume that kakashi (sadly) can't use the susanoo because he isn't an uchiha (doesn't have that chakra)

So what I wanted to say is hashirama will need to trasplant some madara cells in him so they produce that chakra and he uses it combined with his chakra to awaken the rinnegan

(Still this is only a guess)
