I think he can; senjutsu is taking nature's chakra, he already has chakra; if Kishi cares to explain why the actual f**k he can not use ninjutsu and genjutsu; we can make better assumptions; but in my opinion it is theoratically possible; he can control his inner gates which is related to his chakra coil system; and he is doing that more effectively than any other shinobi maybe except for Gai, which is something hard to do, so if he can master it, i think he can handle nature's chakra. But even if that can happens, i can't see in the plot most likely. But it would be a cool thing to happen.
