If the ATLA team could add to their list of potential films in addition to those about Zuko, Kiyoshi and Korra... I suggest a film about the love story of Lin & Tenzin. I want to see that. The film could feature all the children of the gaang. Lin, Suyin, Bumi, Kya, Tenzin, Izumi, etc. The film could explore the weight of the legacy of the elders who became legends after saving the world. How do you carry the legacy of these ancient heroes as their children? How do you find your own path? It could be a great theme. Not to mention finally showing us the love story between Lin and Tenzin (we wouldn't see the breakup, but the beginning of their relationship, and perhaps the seeds of what will happen in Korra). I think this film could take place roughly between the ages of the characters in the original show and the film. Between 16 and 19 would be ideal. It would include moments from their lives up to that age and the adventure they will experience that will shape them for their future. That would be fantastic.
