When Shunsui revealed himself to be unharmed, showing up behind Lille, it hit me that the Shunsui that was shot might have been a gigai made by Kisuke, used to trick the sniper to reveal himself.

I also wonder if Kisuke might have made gigais for more Shinigami, so that the vice captains that were sniped off could have been fakes. Kisuke's in the group, so it's a possibility.
