I take Amaterasu out, just because i want a fair fight, and don't want to see things like: "Sasuke burns Kakuzu with Amaterasu and it's over".Why can't he use Amaterasu? Taking away something like that is just dumb, and doesn't make any sense...
Arrow couldn't go through Kakuzus doton defense. I highly doubt that.Sasuke has chance, When he fought against Danzo, he is not fully powered. Tired of fighthing against kages. Danzo underestimated him but He did well. I will say Sasuke even without Amaterasu. Susano'o arrow is enough too.

But it won't be that easy to land raiton jutsu on Kakuzu. Just look at the fight between Kakashi and Kakuzu and you will see it. Sasuke will also be outnumbered by Kakuzus monsters who could overwhelm him.If Kakuzu split his heart from him, arrow will be useful.It would be like duck hunt. He has kind of chidori jutsus too. He is able to go through Kakuzu's Doton defense like kakashi. Then Arrow will be useful. He can parry his attacks with susanoo rib cage or full susanoo. Susano'o highly defensive against ninjitsu.
