My theory on why the avatar's reappear at certain ages (like when roku comes back when he's an old man while kyoshi comes back much younger) is that they are shown at the last moment in which they used their avatar state. Example, roku was an old man when he went into the avatar state to fight that volcano then died shorty after. Kyoshi, despite being as old as she was when she died, may not have had to use the avatar state since defeating chin. The avatar state is something I'm sure a well disciplined avatar will not use willy-nilly. I don't know, it's just a theory. Going with that theory I believe we'll see Aang at the age we see him in the flashback as he is shown in the avatar state fighting Yukone whenever Korra talks to him.
