Oh yeah, I've seen that one before. I think its a cool legend, and its something that definitely suits a pokemon as creepy as cubone/marowak. And I like the idea of having a pokemon evolution line that symbolizes the life/death cycle. I almost wish GameFreak would make that part of the game, have female cubone evolve into kangaskhan if a special item is used on it. I'm thinking either Holy Water (to purify the cubone skull and allow it to be removed) or a Marsupouch (a fake pouch to stimulate evolution to a marsupial. Kind of like how the Oval Stone prompts Happiny to develop a real egg).
Better yet, the evolution could be started by having a chansey use Softboiled on a female Cubone in-battle, since Chansey eggs are filled with happiness (and presumeably fertility, since Chansey always have eggs regardless of whether or not there's a male around). If the cubone survives the battle, she will immediately evolve into Kangaskhan.
