If it were done it would need to be only certain Japanese planes. Since it fit with the warrior culture and ethos of the Japanese I'm sure almost every Japanese plane had a story of being used in this manner. Some research should be done to see which planes were used by these specific units for Kamakazi missions. My guess it would only be fighters, no Vals, Kates or Betty's. And just from memory (subject to being very wrong) all I remember reading about was one 500kg bomb.
Certainly a plus for scenarios, maybe for MA. What would be fun for scenarios, down the road would be the Japanese Cherry Blossom suicide rocket. Tail end was a rocket, front end was the Japanese Long Lance torpedo, small wings limited range. Carried below Betty and Sally Bombers. Had to get within 10 miles, I think.
Imagine a scenario where a bomber pilot drops this, bomber disappears and the pilots shifts to the rocket cockpit. It would require a real coordinated BARCAP to get the bombers before the released, and high F4UCs to dive in as last ditch effort to get the Cherry Blossoms as they tried to make it through ack.
Could add to scenario, maybe even MA.
