Sorry I read it as the bombs were still attached and you were putting the bombs and plane on target. Didn't realize you meant actually release the bombs.
So what you are saying is:
1) Designer designate a certain plane type as Kamikaze.
2) This plane to have a different point value than other planes when killed
3) To score the bombs must hit and explode and the Kamikaze plane must die. If he doesn't then no difference between him and normal bomber / attack plane.
It is issue item three that would be the issue. If it not required for the Kamikaze to die then technically he could dive bomb from high alt, pull out, and head for home. Or he could level bomb and then head for home. From the logs we know the bombs hit but nothing else. No idea of alt, level or dive bomb, etc. So to simulate we would have to a death recorded ... either crash or death in the logs shortly after the bombs.
Other question is what if he doesn't die? The damage will still count but he didn't simulate a kamikaze which is why his plane has less point value.
You would also have another possible issue even if he does die. What if he releases from high alt, so outside of the effective AA guns. Then he goes and crashes afterwards. Basically making sure he gets his bombs on target. However, a real kamikaze could be stopped by a well place shot at extreme short range. In this scenario the kamikaze can't be forced to do a short range attack. No good way to simulate it.
