I don't think it should be added, but if it were I'd say a perk price for the Ohka paid for by the Ohka pilot and then the Ohka pilot would need to ride in the Ohka's cockpit while the G4M2 pilot carried him to the drop location and released him. He'd be putting his trust in the G4M2 pilot to not throw his perks away.
The perks would be lost of course.
Just like a while back someone wanted V-1 rockets to fire, you could use ..... X amount of perks to fire one off at an enemy base - I laughed at this because the chances of the V-1 coming within 2 miles of its target were bleak - so you would spend 5,000 perks to have a V-1 fired at an enemy town only to have it splash into the ocean.
We don't need suicide rocket planes in game anyway or Launchable V-1s, next thing people will ask for the A-bomb again.
