The Empire Arrives / Adeptus Arbites

I had an epic idea.....Creating a Inquistion Force based on the new Empire Range

I have already acquired a dual hammer Warrior Priest to use as an inquisitor and earlier I was looking at it and thinking bluddy hell this could be epic....

Here is the rough idea:

Warrior Priests = Inqusistiors
Master Engineers = Assasins/Techmarine = Mainly Engineer with Rifle as Vindicaire
Handgunners = Acolytes with Hot Shot Lasguns
Crossbowmen = Acolytes with Storm Bolters
State Troopers with Sword/Shield = Crusaders
Empire Greatswords = Death Cult Assasins
Flagellent Warband = Arco Flagellent
Monkey in the Handgunner box = Jokaero Weaponsmith
Empire Mage = Inquisitor that is a Psyker


Only henchman models not covered:

Banisher
Mystic
Psyker
Daemonhost
Inquisitorial Servitor

although out of that list the only thing that really interests me is how to make a servitor and psyker.....as pretty much everything will go in chimeras or some other mad contratation that i can think of.........
