hey warwick, a fun build you might want to try
Lady Jehanne with 10 battle nuns in her troop.
add in Isarah, Cleric of Shadarzaddi to cast burst of speed.
and Halbarad, Priest of Aurellius for bless
so they all get to move, then focus for a plus 2, and martyr for 3.
you now have 10 models that can do 3 at 8.
and so not to waste her warlord ability id take a group of archers with a cheap melee leader and run him in to kill and get killed, then regroup the archers so they can start focusing with a plus 2 focus and bless(total of plus 3) to finish off whats left. and you still have plenty of points left over to take what ever you want.
have fun :)
