I deleted all the unnecessary information from your post, and added the idea below:
I wish we could add a hockey-style mini game where players will be set on random teams. I wouldn't know how the hockey puck and hockey stick will work, but I think this will be a very good idea. If this mini game gets popular, we could host community events with 4 player teams into tournaments or shootouts!
As for my reply:
As for the idea, if you don't really know how it will work, then what is the point of suggesting it? I think hockey would be cool, but I think this idea isn't possible for minecraft. There isn't really fluid movements in this game to make it enjoyable.
