You have too much $$$ and don´t know how to spent them properly?
You like to gamble?
You love lootboxes?
Great! Here comes: Sub(scription) Roulette!
Here is how it works:
1st you pay (4.99$) for a subscription
2nd you´ll be thrown into a random Twitch Live Stream
3rd Your subscription will be shown live at the stream (just like usual subs)
4th congratz! You have just subbed to a random streamer! Enjoy your emote(s)
5th repeat 1st! (optional)
Sorry if this idea was already invented and presented by someone else
Edit: To make this more attractive, Sub Roulette "Players" could get a special emote made by Twitch, just like Twitch Prime users get MiniKappa e.g.
