Dont mess with the squads
They can fly what they want and the break between them. Only caveat is they may not switch aircraft during the frame.
Knights could fly all fighters then any dead guys could wait for the Kamikaze run later in G4M1s.
I noticed that have a mass group of Kamikazes is not very good, draws them like sharks and makes having highter Japanese fighters to interfer more difficult to time exactly. Launch all at once but assign some groups to hold outside of cover and attack at different headings over a longer period of time. If the G4M1 pilot\AI group survives its torp run it will have up to 4 torps in the water enough to take down any carrier. Only experience AI bomber pilots should take AI with their Kamikaze run otherwise you are just giving away points.
