Multiplayer multiple consoles Minecraft Dungeons

Have the ability to have Main account and guest account on one console while still be able to play online with a friend or 2 on another console. I would also make it so more than just 4 players are allowed to play at one time, just scale some of the difficulty with it (more players, mobs have higher HP.) Create like a weekly raid boss that drops something like "Increases item level of melee/ranged weapon, Armor, or Artifact by +1, +2, +3 depending on difficulty and size of raid group"
