Actually, Chishio, the purebred Heartless ARE hearts that have fallen into darkness, while the Nobodies are the ones without hearts. The heart that leaves the body as it dissolves is the heart freed from the excess darkness binding it, from what I understand. My theory falls into the Heartless Grimm category, though, regardless. On the switch, Heartless can only be permanently destroyed by the Keyblade, making me think something similar could be true of Grimm - they just respawn in a younger, weaker form when they are slain.

Live, I do like your idea, though.
