[Suggestion] Mini Great Hunt Bosses

It would be really cool if great hunt bosses were turned into mini bosses on other maps so you can gather the material they drop and use it. But of course the first requirement is that you have to beat the great hunt on its respected map. Before they can be free roam everywhere else. I'm asking for this as a way to make the game a bit more engaging. Since maybe you don't know if you will run into one while exploring and such, and it would be a great way to make the things you unlocked from then still relevant.
