I don't have anything specific to contribute, but I'm all for the idea of getting more and more npc emotes. I think any almost any and all emotes that npc have should be given to players. Imagine how many unrewarding pieces of content could instead have a slew of fun rewards if all npc emotes, furniture (just look at the hundreds of furniture items sitting around in the game that players can't use in their own house), mounts (half of all the monsters in the game look perfectly designed to be mounts), etc were added for players. And that's with so much less additional work since they're all already created.
