Out of Shokaku and Zuikaku the only other I can imagine using it for a Kai ni is Taihou (but her kai is at level 40 so if she get a kai ni it will be level 80/90

"Taiho‍ '​s original design specified installation of two catapults on her forward bow for power-assisted take-offs. However, as the Imperial Japanese Navy had not developed a workable catapult for carrier decks by the time of  Taiho‍ '​s construction, these were eventually deleted from the requirements."
