Your Archon is very expensive, you should drop the PGL, grotesques are only I4 so striking at initiative not important for them. Besides they are tough enough to stick around to strike back. As for the ghost plate armour I wouldn't bother as normally when your shadow field fails you Archon is toast from instant death anyway.
