The number of pilots would certainly be very limited. The Kamikaze system was successful in mass recruitment (although not pilots were volunteers) thanks to a very complex set of social constructs that were unique to the Japanese culture, with elements dating back to before the founding of the Great Shogunate.
Those elements were entirely lacking from German culture. You would have a limited number of pilots who would grasp the nettle, most of the rest would have taken off headed toward WAllied lines, dropped their landing gear and lowered their flaps in hopes of surrendering or at least gotten as close to the WAllied Lines (which were only about 10-15 minutes flight time from what was left of Germany) and bailed out.
The mission was a death sentence. The first time it was tried, of the 12 pilots who actually engaged (of 180 who took off on the mission, which itself speaks quite eloquently as to the enthusiasm of the crews) seven were KIA, four were WIA. One came down unhurt. The managed to down 8 bombers (the worst part is that the pilots who conducted conventional attack and AAA shot down more bombers than the poor deluded bastated who tried to ram). That was BEFORE the escorts had figured out what was happening.
Exactly how many Luftwaffe pilots who do manage to bail out are going to make it to the ground alive once the Americans twig to what is happening?
