sure, We'll tweek the years a bit.  I can adjust my age too.  It doesn't have to be exactly twenty years later.  I can also fix the history portion, as I wasn't actually clear on that.
How do you want things to have happened?  The four main Red Lotus members surviving could work.  I'll have to push up Korra's death a bit, and say that the Air benders and team avatar were unable to stop them after they killed her.
