All previous game modes

Am I the only one that feels that we should be able to make custom games with previous game modes, such as U.R.F. mode or Doom bots? I really did enjoy these game modes with my friends, but they left way to early. But I feel like if Riot had put in a custom game mode for the special game modes, many people would be satisfied to receive this. My personal favorite mode was the "All for One" game mode, where all champions on the team were the same. Imagine re-playing this with your friends. Like, for me, it would just be a flurry of Thresh hooks and Teemo Mushrooms. It was a fun experience that I really would like to see again.
