I never though about using drones for the kill team, thats pretty imaginative. Here is what I thought about as far as a kill team, it has several different types of models to give it some variety and only 1 Heavy Weapon, the Rail Rifle. Although I did break a few squads, I had to in order to make it a colorful unit.
Shas'vre Stealth Suit w/ Burst Cannon, Bonding Knife, and Gun Drone (55 points)
Pathfinder w/ Rail Rifle (22 points)
Pathfinder w/ Carbine and Photon Grenade (13 points)
7 Fire Warriors w/ 4 Pulse Rifles and 3 w/ Carbines (70)
11 models for 160 points.
