I still think an Clan-techie, flipped, turned spy and agent for a House, is the best route to go. In Mechwarrior, RPG, it would give a good use to the fast-talk/persuasion-skill.
In ASoIaF, RPG, they treat social as just another form of combat, like physical, with NPCs/PCs being defeated, mentally. Perhaps there are some good rules in Mechwarrior for that.
