Sticker idea

So, from what i've heard from these stickers, they seem similar to gifs. But what about instead of doing that, you have them basically animated emojis? Instead of having to pay $10/$5 a month if you just wanted the emojis, you could pay a buck or something then have an animated emoji that you can use when you want to. 

Doing this would make it so that people would be more inclined to buy them, since they can just have a one time payment instead of $10/month just for some emojis? And then this wouldn't really be better than nitro, since with nitro you'd still get all the emojis from the servers your in, but say you just wanted like 1 or 2 emojis, you could just pay a couple bucks and be able to access these emojis.
