One interesting plot twist could be that as a girl, Jack Frost has to deal with different social expectations in the magical world. For example, she might be underestimated at first but then prove herself to be even more powerful than the male counterparts. Another could be that she has a unique connection to a female - centric magic that no one expected, like being able to communicate with certain nature spirits that only respond to female energy.
Characterization is key. A good Blair and Chuck fanfic should have them act like they do in the show. Blair's strong - willed, sophisticated nature and Chuck's charming yet brooding persona need to be spot - on. For example, if a fanfic has Blair cowering at the slightest problem, it's not true to her character.
