It depends on how they approach it him trying to figure what it means to be a superhero. That was a recurring joke in the claremont/byrne run where he joked about not knowing what to do as a "fledging superhero ". (He was pretty young in the comics)
In the comics, the role of the Iron Fist isnt given an exact goal/duty outside of acting in Kun'lun's interest/defense. So maybe that could be his arc?
