[ATLA] If he wasn't frozen, could Aang have ended the 100 year war?

It all depends on if he gets caught up in the genocide or not.  Aang as he was wouldn't be able to stand up against an army of fire benders hopped up on comet, but if he manages to escape and seek refuge with the Water and Earth nations to complete his training and realize the Avatar state like he does in the main timeline, yes, he would be able to stop the war.  

We see several times that not even an army can stand against a fully realized Avatar.
