You'll definitely need some more high leveled CA(V), at least 2 CA and 2 CAV at the minimum level of 50 would be good, preferably at level 60. CLT are the boss killers, so you should aim to grind at least the other CLT to Kai Ni - Kitakami and Ooi are some of the few ships what are truly necessary for some maps, such as Winter E-5 Hard Mode (easier modes can be cleared without a CLT, although it'll probably be noticeably more difficult without them).

4th High leveled CV would also be good, I recommend grinding Zuikaku for some 40 levels or so from there.
