I do think Ku is Kozuchi, but I think he's a lot younger than was presumed by the theory. I don't think he was Garaga's summoner and I don't think Orochimaru is involved. My theory, is as follows -

Kozuchi got injured at some point (Presumed deceased) ala Obito. He found a way to use the Akuta kinjutsu to make himself an army ala White Zetsus. Problem being, these things, along with his clone soldiers (Discount Sound Four) have a limited lifespan, so he abducted Mitsuki on the basis that it's easier to get him out of Konoha than to try and attack Orochimaru directly. Through Mitsuki, he hopes to unlock the secret to a proper lifespan for his army and take his revenge on those he perceives to have slighted him and probably bring the ninja wars back to full swing with Iwa at the head, since the anime team keeps hammering the war is bad and let's all move on angle.

This is less a theory than mostly the blatantly obvious at this point. What I do think is odd, is that Lord Ku and his crew seem to be holed up in the Tsuchikage's place, or at least the former Tsuchikage's place, as Kurotsuchi's office seems to be all big and sparkly by comparison. Or maybe a lot of buildings look like that in their country, I'm not sure.

Still, while Iwa was generally militant in the past, I think this is a case of something they didn't want dragged back up, like Deidara and the kinjutsu, so it's likely that's part of why Kurotsuchi didn't want Konoha nin in her country, less this reflect badly on past decisions of her predecessors.
