Just chatting - pair with another random just chatting streamer - chatroulette ish
When streaming in the category "Just Chatting" allow the streamer to have a button that would que them to randomly pair with another streaming in a chatroulette like fashion if that other streamer was also in que. Make the chat screen split with each streamers separate chat rooms battling in a way. There could also be a button that would allow all donations to split evenly if both streamers clicked. If not, they would keep all donations made from their streamers. Would be a great way for the community to engage.
