chest loot - chess pieces collectables

I think a cool set of items to be seeked in chests would be chess pieces. A grand enough mission could see players complete their set of both colors. the blocks already make a nice chess board. Maybe each kind of piece would be found in a specific biome, queens and kings only found in ancient cities, pawns in regular villages, rooks, knights, and bishops to be found in abandoned mineshafts. 

This wouldn't add much in the way of standard minecraft gameplay, but for example my family shares a world, and we use minecraft as a family game, where playing minecraft may not always be minecraft for us, but just a familiar place we can all be in at once even if we are far away. 

The pieces wouldn't do anything, but players could place them and pick them up and play the game as they would irl.
