I know i'm going to get shot down for this, but what about
ME-163 Komet - Come on. Who doesn't wanna be blasted up into the air then come down and ram some buffs?
Yokosuka MXY7 Ohka (Baka) - This would be amusing for attacking carriers and PT's. Ok, totally unrealistic to expect this one. I was reading about it the other night, just found some info online.
