Ok here is where I landed. Looks fun as hell and within the rules except where noted below. Assuming 32 point buy here but use your own point buy rules if you want. This character concept makes for an awesome, nimble but deadly Rocket Boot Jockey of the underworld, Jet Pack Trooper in a military concept or Huttball ball runner (a form of football Star Wars the Old Republic).
I was able to find some suitable "armor" that looks more like regular clothes. The Swoop Biker's Garb (as Padded Flight Suit; see Dawn of Defiance 2; pg 17) allows you to basically make your own outfit in terms of look. I imagine it as Coruscant Entertainment District Underworld street style.
This is a highly mobile build. The Long Strider talent grants Move Speed 8 and with the repulsorlift armor upgrade activated you can ignore difficult terrain and take 1/2 damage from falls for 40 rounds without recharging. The Sidestep talent permits diagonal movement without the 2x cost with just a Swift action. And of course Rocket Boots (as Jet Pack) add the ultimate in Star Wars cinematic mobility!!!
Defensive capabilities start with Running Attack to permit highly mobile strafing while staying behind cover. The Dive for Cover with Skill Focus Jump and the Jump Servos armor upgrade makes this PC or NPC able to avoid one attack per round, landing prone but behind cover. With a +16 Jump and the Jump Servos, the PC can jump 4 squares horizontally by default before any roll. The Jump Servos allow you to take 10: you can jump 6 squares by taking ten.
Lastly, this build packs some punch with a blaster pistol build and an Ascension Gun that adds further utility and mobility.
