Would be nice but if you had a whole team of people with that aura the npc's would soon run away in fear yelling
"OMG ITS MR.BLOBBYS GOONS AFTER US AGAIN! RUN FOR YOUR LIVES!!"
Union:
"Farah O." Stalker: Street/Energy
"Aoi" Scrapper : Kat/SR
"Supa Troll" Tanker: WP/SS
"Milkman Bill" Brute: Staff/Fire
While I dont really like the way the Combat Auras work in the new Cyborg pack (only showing up when in combat mode), I do like the holographic mask aura thats part of it.
It got me thinking that itd be cool to have more holographic auras e.g. full body holograms could expand your costume parts or your could add holographic shields (like some of the new chest plates) or whatever.
Just a thought.
