I think it would of been fine if Kuma's story ended with Kuma's death
I think it still will. A Gorosei orders S-Bear to kill Bonney: but, Bonney commands all Kuma Pacifista.
Bonney orders, without thinking, "Dad... please, remember me!:
S-Bear takes this as a legit order, and takes Kuma's memories, that Bonney got from Vegapunk's Secret Chamber with the Kuma Memory Bubble, and absorbs them.
S-Bear becomes a Kuma Satellite, like the other 6 Vegapunks are to the Stella, and OG Kuma rests in peace with Ginny somewhere else.
Vivi gets the Paw Fruit.
