As an addition to the current Level Leaderboards, I propose that we could possibly add some for all of the sub areas? This was just a random idea I have had recently

The big problem with this category is that it favors people who have a lot of viewers on Twitch. The streamer could just have his audience make balloons that are close to the starting point. The less popular people have to take around 20 to 30 seconds to get a balloon. I see what you were thinking but it is not the best when fleshed out.

You complete the game while getting all moons that are in 2d or are part of a 2d area (like Past the Chasm Lifts in Cascade). Will be like All Sub Areas in that you have to start from a new save file.
