Allow streamers to make their own unlockable Hype Train emotes
Ever since Hype Trains started in January 2020, there have been three "seasons" of Hype Train emotes. It's been a year and a half and the pool doesn't get updated with any kind of regularity. While this is a subjective opinion, I consider the global Hype Train emotes to be a bit underwhelming and I don't really see them get much use.
Considering it's been a while since the third round of emotes, my proposal is to allow streamers to create their own Hype Train emotes. Partners and Affiliates can make up to 15 emotes (3 for each level) that can be unlocked. Once a certain amount of users have unlocked all 15, that would create another Hype Train unlock slot. For example, if 20 users acquire all 15 emotes, then a 16th emote could be added at Level 1. 20 more, then a 17th emote at Level 2, and so on either indefinitely or a cap of a certain number.
