Custom emote rewards
The hype train is such a cool way to show support and to get everyone in a good mood for a little while, but the emotes offered leave a lot to be desired. I believe people would be much more inclined to support a hype train if streamers were allowed to put their own custom emotes instead. No one really uses Twitch's provided hype train emotes. It would be a really good way to reward supporters by offering them permanent emotes that they would actually be excited to use.

I love this idea! This will definitely allow for more interaction with Hype Trains and it gives the viewers rewards after the Hype!

Custom Hype Train Emotes!
Allow streamers to upload their own emotes that are given out after a hype train!
Gives more motivation to start hype trains and collect all the emotes as well as gives a more unique experience in each channel so the people supporting will get complete different emotes in different channels!

I wonder if we could add a short sound to the hype train when reached. A very simple alert or something. Sometimes when playing competitive games I may miss the hype train because of that. Of course this can be optional and not a mandatory thing to add for each streamer. BTW Calidorii, Great Idea. Ty. (:
