Allow nitro users their own locally stored emotes

Now this post might sound crazy or far-fetched for some, but bear with me here; I understand Discord Nitro is heavily invested in the whole idea of allowing Nitro users to use emotes from the servers they're in, anywhere... but I think there is a great way of improving on that benefit, while keeping Nitro profitable and worth subscribing to. My proposal; to grant the Nitro users the added benefit of having their own, locally stored emotes. The implications of having locally stored emotes are: Nitro users wouldn't have to join and maintain activity in a dozen of servers solely for their emotes, and Nitro users would have access to more of their beloved emotes, without the need to join a ridiculous amounts of servers that, again, they would not be active in.

I think having the ability to use the emotes from your favorite servers globally is great, but I believe improving on that with the added benefit of using your own, locally stored emotes is better.

TL;DR: There are no negative implications to this that I am aware of. Users would have their favorite emotes in the form of a common picture format (png, jpeg), and would send them through Discord, thus shrinking and caching them on Discord so they wouldn't have to upload a new picture every time they send the same emote, as emotes and pictures already work on Discord anyway.

P.S: I'm all for server emotes, I just think joining servers JUST for emotes is pretty redundant.
