Move the Grey Knights to the Fast attack, and add some more ISTs. If you foot slog the ISTs you need some more numbers, so maybe 10. Also if i'm not mistaken GKs have something that keeps psykers from attacking them, so you can dicth the Psychic Hood.
Note: To get cheap ISTs get a box of Cadian Shock Troops, add a bit of wire from the gun to the backpack, and you got yourself 20 ISTs for 30 dollars cheaper.
