I mean, why not? He just needs to trade one random peasant for her. A piece of cake for the most powerful Dark One ever.

As far as I remember Hades had nothing to do with that. It was never mentioned. That's why they killed Robin the way they did. Otherwise, it would be easy to bring him back True. But let's think IC (in character). Rumple would never try to kill Belle, even if he'd could ressurect her. He never leaves things to chance.
