Minecraft multiplayer, on 1 screen!!!

This would work better as a different game than an add on.  just Minecraft with Minecraft Dungeons screen layout. when 1 player is mining, the screen could split in half, (or more, depending on how many players are mining.) If a player goes away from player 1, the screen splits. Player 1s side, and player 2s side. (or however many players go in different directions.) and, finally, creating your avatar. It should be like, a pixel graph shaped like the Minecraft avatar. There should be a bar of colors you can choose from. Also, 2 options for creating your avatar: a pixel filler, filling 1 pixle, and a chunk filler, filling a part of the body.
