It should not be too hard,its basicly a speadsheet running besides Destiny. If a website could do it I don't see why it can't be ingame,it should not take up much space and bandwith at all. And then you have the pro,s of such a system like being able to inspect a character in real time and check his build,they can even sort by country/region/language. Hell you could even check if the person has a mic the console does that standard for you,why not make use of that? Ah well gues they are too lazy or just don't prioritize something that would make things much easier.
