i'm not sure what the purpose of such a companion would be, though, and your initial post didn't really make it very clear. i'm not familiar with swtor myself, so i have no idea what this companion system of them entails... is it anything like our chocobos in that they'd help you fight? if so, i don't really see much point in them to be quite honest... im guessing such a companion would fall under the bodyguard category you speak of, but what would be the function of a "lover" or "friend" companion?
right now it seems to me that you're offering to pay 25 bucks for a glorified minion of light, that changes forms every time you summon it :/
