Hook only got to come back because they took care of Hades, and Zeus was in a good mood. That was a one time thing. You can't just take somebody out of the Underworld normally. Not unless a living soul trades places with them. Or you split hearts, maybe. (But Snow and David already did.)

Even if they didn't split hearts already, I'm not sure it would have worked. David briefly died from having his heart crushed, so in a way it made sense that Snow giving him half of her heart saved him in the brief time window available. Would a split heart revive somebody who died via other means?
