You can just use 3 CV in terms of using Combined Fleet Carrier Task Force, while flagship is like CAV or CA, then rest are BB, but this changes if you want to use Surface Task Force which will only allow 1 CV or 2 CVL, which might not be efficient if the map Combined Fleet is required has like air superiority heavy enemies such as Wo-class Kai flagship :x

Well it will depend on what kind of maps will fall upon us.
