Idea Mini buildcomp on build

What do you guys think about having the command /comp <username> on build so basically when someone does this command the other person has an option to accept or decline it. If the other person accepts both players will be sent to a map where there is a theme and they have to build it, when its done people can vote on what build they like better after people have voted the map resets, it's not just one arena, a lot of people can play at once like for example 2 people can compete in one room and 2 people can compete in another room
