Give Streamers the option to use a certain amount of Emotes (Maybe more for Partners or something like 1 + 1/10 of your unlocked Emoteslots rounded up) to be unlockable by Channelpoints but not by Subscribing or Cheering. Every Streamer can chose the cost of the Emotes they want to have themselves.

This allowes Streamers to give something back to the Community and makes it possible to get emotes by just watching and being Active in the Stream and the Community when the people cannot support monetarily. This also still incentivises to Gain More Subs due to getting the possibility to unlock more slots.

An Example for this would be unlocking Special Raid-Emotes that Viewers get to be able to join raids fully with emotes.
