Rotating Game Mode Additional Game

Just out of curiosity what are the odds that Riot adds Black Market Brawlers to the rotating game mode. I always thought this was one of the coolest events that they ever pulled off. Not to mention that it is still one of the better designed modes. I know a handful of people that share the same sentiment so I'm sure there's a good amount of old players that would enjoy it, as well as newer players who never got to play it.
