The Piranha could definitely be an interesting choice. However, adding it (and keeping ATS on the Stealthsuits) just further reduces the bodycount in a closerange army that's (a) essentially dronefree, and (b) very weak to psyker powers and mortal wounds. If you want a Piranha here's how I'd do it:

HQ  Commander w/ 4x Fusion Blasters; 2x Gun Drones (176)
HQ  Commander w/ 3x Cyclic Ion Blasters, ATS; 2x Gun Drones (154)
Elites  5x Stealthsuits w/ 5x Burst Cannons; 2x Gun Drones (166)
Elites  5x Stealthsuits w/ 5x Burst Cannons; 2x Gun Drones (166)
Elites  Ghostkeel w/ Cyclic Ion Raker, 2x Burst Cannons, Target Lock, ATS; 2x Stealth Drones (181)
Fast Attack  5x Pathfinders w/ 5x Markerlights (40)
Fast Attack  5x Pathfinders w/ 5x Markerlights (40)
Fast Attack  Piranha w/ Burst Cannon; 2x Gun Drones (71)
Total: 994  Command Points: 5 (1 Vanguard Detachment, 1 Outrider Detachment)

Still some points to spend too. What do you think?
