[The Last Airbender] What would have happened if the Air Benders had been completely eradicated before Avatar Roku had died?

EDIT: Air Nomads. The whole nation.

The Avatar would have been born to an Air Acolyte couple, had a shitty time trying to master Air Bending, and probably die trying to fight the fire nation.  Then we'd get a Water Tribe Avatar, who would have an even shittier time trying to master Air Bending, and also die fighting the fire nation.  Repeat until Harmonic Convergence, which Unalaq pulls off without a hitch, which spits out a lot more Air Benders than it did in canon.
