Rotating Custom Games

I wanted to know if there are going to be custom games for rotating game modes, I think it would be really awesome to have fun with friends like we did back in the old days where we can create customs using other game modes. Things such as hide and seek or just have fun with more than 5 people in the game mode, rather than just having a 5v5, 4v4, etc all serious like. Especially for the new project map we are getting ~i think [sg-ahri-2] If you can tell me why this wouldn't work this would be appreciated. :)
