No. The lack of significant aircraft utilized by the Japanese leaves big gaps in PTO setups. The Ki-43 and G4M were used in virtually every campaign from the beginning of the war until its end, and yet we don't have them. They are a SIGNIFICANT order of magnitude more important to completing the PTO environment than Kamikazes would be.
For that matter, even DURING the war, the Kamikaze was largely just a footnote, and a VERY small part of the overall air war.
Special events and FSO are NOT designed to be perfect living history events. They're designed to balance history with PLAYABILITY. And Kamikazes would NOT be enjoyable gameplay for either the Kamikaze themselves, or the players expected to defend agaisnt them (think about how fun it is to defend against suicide pork runners in the Mains. Now multiply that by entire squads doing it).
Have you ever even FLOWN in FSO, a scenario or snapshot?
