Is it possible to make URF in a custom game like how ARAM used to be?

I'd like to bypass Riot taking away URF as I'm not done with the URF game mode yet. Does anyone know if it's possible to create a custom game with custom rules, through mods or something? I know there's other people that still want to play URF, and if you don't, you don't have to play it, but in a world where anything is possible on the internet, I'd like to see if there's a way to make our own URF.
