/Equalize
I recently saw a PBE video where the winning team was able to vote to equalize the game, giving gold and exp to the losing team, and equalizing the tower count. I feel like that would be a pretty bomb addition for normals or aram, where I'm not always looking to stomp and just want to have a close game. It seems like it has to be unanimous as well.
Here's where I found it. https://youtu.be/fc54Wr-vZDc?t=20m28s
