Well assuming your technique works, and that's a mighty big if. Bocc is in a little trouble. He won't die right away, but his current body will be unable to mold any chara indefinitely and by extension perform any techniques. Malnutrition takes a long time, so while that idea is plausible, it isn't instant. Though it is debatable if he'll die from lack of chakra, like Kakashi did during the Pain arc. Although Kakuza didn't die right away, but that doesn't mean he wouldn't have due to lack of chakra (Though in my own words, no scans = no proof.)
So IF your attack goes through, Bocc won't die right away. He might die from no chakra in a bit (debatable), but he won't be able to use any of his own chakra and be blind if you also struck out your eyes. So assuming that chakra depletion doesn't kill him, he'll have to fight two Oto nin blind, using only 4-6 tails of Kyuubi chakra. He claims six, but I forget if it's allowed that you can master tails while in a fight. This is also assuming that even with Kyuubi chakra he can even perform any techniques, as when Kakuza got stuck, it was stated he couldn't ever perform a technique again. So if you don't kill him, you've severely weakened him.
This is all speculative and assuming your attack goes through, which still has many factors impeding it's success
