Tatara's biggest purpose in the story wasn't his hatred toward Houji, but rather his relationship with the One-Eyed Owl. Why Eto and Tatara were such good friends is still a mystery, just like the reason why Donato didn't kill Amon back then. Seeing how Ishida highlighted their relationship during the whole story, expecially during the Rushima arc, we'll most likely get a flashback which explains everything. On the other hand, the Chi She Lian stuff isn't that revelant to the story ( as long as the organization didn't have any connexion to V ), so I guess Ishida can explain it in a spin-off.
