I know, I'm trying to see how many captains remains. Although you're right, I forget there's more than the 11 captains.

Although Byakuya isn't strong enough to fight yet, there's 5 Royal Guards + Kisuke, Isshin, Tessai and Love, and Ichigo. So there's 20 captain-level Shinigami vs. 23 powerful and slightly overpowered Sternritters.

The Fullbringers could be lucky and make some damage if Kubo write the story in their favor and match them with the right opponents.
