Katara could also be a main character, perhaps with her waterbending skills being even more refined. Zuko too, as he continues to deal with the Fire Nation's future.
One interesting concept could be new bending techniques. Maybe the fanfic explores an advanced form of waterbending that combines with spirit energy. Another concept might be the introduction of new characters who have unique relationships with the existing ones. For example, a new airbender who has a different philosophy about peace compared to Aang.
