Fuck no!
This is terrible.
Zoro was never an ittoryu user, he only goes ittoryu for specific attacks like SSS. Even has a kid against Kuina he used nitoryu, which is basically his "base" form.
This drastically increases the chances of King getting one shoted unless Oda decides to develop ittoryu Zoro all of a sudden.
This is garbage. King deserves full power Zoro.
