I've seen many datapacks that add player heads in survival in different ways, such as trades and players killing each other. But this is my take on it, in a more vanilla approach: letting yourself die to a charged creeper like the other mob heads in the game. Unlike vanilla, I tested to make it so that it would follow the vanilla rules and let it only be 1 head per creeper, but I think that's hard-coded in the game, so not really possible, so when you go to blow yourself up you can tag a zombie or something along with you to get the head from that too, also works if more than one player walk up and die just make sure to take off your armor lol. I've lost a couple of creepers that way. My bad.
