Definitely it isn't a bad idea, I'm pretty sure that emotes where designed with that kind of social interaction in mind.
Although that's not the focus of the game, they really need to work on a bunch of things before even thinking about adding that sort of mechanic.
Just look at the bells in FFXI, those things weren't popular even at launch.
