I don't know how Sommers is going to kill the supposedly "dead" Kuma. If Sommers can make Kuma really die this time which I don't think it is going to happen because his body is already destroyed. The only reason Kuma can still control the body is his soul and only music, emotion, and Big Mom's DF can interact with it.
Maybe revive is the play here, but he still not going to die anyway because he is already "dead".
