First of all, I don't think Kill-Team allows the use of HQ characters, so your Inquisitor's out. Also, one Psyker's not going to be of much use on his own. I'd also advise dropping the Chimera and spend those points on more troops. If you keep it the way it is, You have 4 troops, meaning if 2 get killed, you'll have to take a leadership test at Ld 8 every turn and lose if you fail. Take more Crusaders and Death-Cult Assassins. Also, you can never have too many Acolytes. Give a few flamers/plasma guns depending on the circumstances, and give the rest storm bolters.
