The series would have the same characters and all but I believe this plot would be different then anyone would expect.
Ok, the series starts of showing all previous characters but lets say time goes ahead and they are all like 5 years older. But what im trying to get to is that Aang and the crew start hearing of a new threat going around wiping out small towns and other small crimes but nothing major like taking over the world. (Ok im not good at explaining things so let me get to the point). The new threat would be an airbender who shows much more skill then Aang did and also does a lot of different techniques. He would be one of many airbenders who lost there way after going so long without having monks to guide them and they all were, lets say in hiding, as to prevent the old fire nation from tracking them down and killing them.
Ok I know I probably explained that badly but in my head its great!
