How about ,
/aim aims your rifle or pistol if a trooper or smuggler, could come in standing, kneeling and prone flavors, all those animations are already in the game, would be neat to have for the RP crowd, I guess it could be /flourish or /brandish but make it a continuous aim down the sights type of thing, someone also mentioned /surrender or /arrest hands behind head or back would be pretty neat to have,
