Monkeying around with the Inquisition and Assassins

I've always found rag-tag bands of warriors far more interesting than the uniform rank and file of the military armies such as Space Marines or Imperial Guard (now Astra Militarum) or massed hordes of Orks. With The Inquisition I think I have found the middle ground I've been looking for with some added spice in the form of some Assassins...

Assassins - Know your weapons

With the new 40k 7th edition Ally rules you could now include Assassins in any army. I've already heard of people making a Sneaky Gitz conversion for their Ork army and there's huge potential for a Daemonic, or perhaps even Tyranid, Assassin.
However, their unique toolbox of weaponry however can take a little bit of thought...

A classic assassin, painted in my youth. He's due a repaint!
