Byzantine Empire AH Challenge

Have the Byzantine Empire in the 6th and 7th centuries reclaim the territories of the Western Roman Empire and by 1453 control all of Europe and Asia.
 
A.D. 503: A massive plague sweeps across the world, killing every human it infects. The city of Constantinople cuts itself off from the outside world and survives. The rest of the Eurasian population dies.

Extrapolate.

I presume the author was asking for something not ASB.
 
Actually, maybe this is a bit ASB. This is a more realistic challenge: have the Byzantine Empire recapture all the territories in the west and be as powerful as the Roman Empire had once been until the early 20th century.
