I would like to share this list i've made. I finde it very fun and competitive.

Manaroo:

Attanni Mindlink

Asajj Ventress:

Attanni Mindlink

Dengar

Kavil:

Attanni Mindlink

R4 Agromech

Blaster turret

Asajj and Kavil can do a crazy amount of damage. At first Asajj had Latts, but i think Dengar is more fun.

It can be kind of tough for Kavil, i goes down pretty quickly because he wants to be in range 1-2.

But on the other hand, if you get 3+ attaks off with him, he's payed off.

I hope you guys like it as much as i do. And if you have some pointers i would love to hear them.

R4 Agromech and the Blaster Turret's requirement to spend Focus to fire it do not interact, and so you won't get a Target Lock. The Blaster Turret is the one turret weapon that really has no place in the game currently, since every other option is a better choice. Kavil in particular is probably best with a TLT or Dorsal Turret (if he also has Vectored Thrusters to close into range for it). I'm not sure where best you could shave the points in order to afford a better weapon, though.
Other than that, it's 2/3's of an established list so there's only so wrong it can probably go.
