How about a champion who would have a special VO line for hexakills?

We already have countless of champions that are saying something in game after a multikill. We have this for every type of multkill, except for hexakills. So i suggest that, it would be really cool if we had a new champion someday who would have a VO line after getting a hexakill. But obvoiously it would be only triggerable in the hexakill gamemode, so it would be a really hard task get this line played. (There could even be one for legendary kills, but im not sure if they are still in the game.)
