Community created content for MC Dungeons and/or Legends

Part of what makes Minecraft so successful is the direct creativity of the playerbase that enriches it. Wouldn't it be cool if map/skin creators could get permission through Mojang to add their own content to the Marketplace on these games? Also adding a marketplace to Dungeons would be awesome! One example of a cool marketplace add on for MC Dungeons is a cool mod that I saw which allows you to play the game in first person. Please consider this Mojang!
