Yeah that system is pretty cool, but the way our game is right now, hero deaths are not really guaranteed to happen, and might be just too rare to count on, depending on the difficulty level. We also don't have a persistent world in the same way, the lands are generated fresh each time. But so yeah those are great ideas, but there's also some distance between "here is a bandit" and "here is an epic 100-year storyline", and that's the thing we're really trying to solve here. Legacy monsters sound awesome though and I'd love to revisit them.
