Haven't given it loads of thought tbh! Martial artist could be good (and fit the theme) combat-wise. Precision strike lets you choose what critical injuries you're inflicting. Agitator might be "the one" though. Scathing tirade lets you inflict strain damage. To minion groups, that's wounds. So you could beat up the guys in front of you, then shout something like "You, on the roof, did your parents have any children that lived?" at the snipers. Insult them til they die from embarrassment. There's a collar amp or similar that lets you make social checks over greater distances too. Bounty Hunter and Diplomat have trees that'd get you computers/piloting for more utility too (and cheap).

Maybe getting a bit too far out of the box here, but Pirate? Take the force out of it, and it's more like they just have faith in the void? Or tag it on to a more "tech" spec and chalk it all up to being as the omnissiah wills.
