Souns good, just add a few units to Palahva, change the unit names and such (i'm assuming only alexander is playable).
Have the KH in the south, take the ma from eb, gie most thing to persia and go!
(Also take away the city walls for most places, if alexandr had to wait 3 months per city and could only march fromPella to Bysantium in 5 seasons he'd be alot slower)
