Thanks for the input guys, as no one seems to have an issue with this I'll do some skins from Kamikaze groups later on. Lyric1 has found photos of some interesting schemes from these units.
It makes sense they'd have used the Ki-84s as escorts for the Kamikazes, apart from wasting their best aircraft the Ki-84 was harder to fly for inexperienced pilots than the more expendable A6Ms and Ki-43s etc.
