For those who dont know, there is speculation, along with hints (lastest planes that are rewarded from rankins will also be reward quests for Suzuya K2 quests) that one of Suzuya's Kai Ni forms will be her reclassification as a CVL, making her a possible stand-in for Ibuki.

I might keep 2 Suzuyas if the upgrade is reversible like Shou/Zuikaku

But then, she might be able to use Seaplane Bombers/Fighters along with regular Carrier based planes

Though what of Ibuki actually? Ain't she supposed to be Mogami 2.0 with improved structural design before going flat top?

That's another reason why it's speculated that Suzuya Kai 2 could really be a CVL conversion, along with the hints from the new M63 fighter-bomber description (重巡改装の攻撃型軽空母などで、ぜひ機動部隊運用を！) and fairy looking like Suzuya.
