To my current knowledge when boosting a character you are unable to complete previous story lines, so stuff like the HK Assault would be unavailable to gain for that character. And sadly they bind on pickup, so you can't transfer it from a different character or buy it from a seller. Hope this helps! http://www.swtor.com/r/XYpZlM
