Freljord game mode

So what if they made a rotating game mode with a special freljord map with different areas kind of like the star guardian game mode but instead it was fighting for control of the freljord on teams following Ashe, Sejuani, or Lissandra. If it were pve the different levels could each be led by one of the freljord champions fighting for control of it. If it were pvp maybe a 5v5 on a special freljord map and one team is with Ashe and the other Sejuani (kind of like Xerath in Ascension but one is an ally the other an enemy depending on your team) and there are different objectives from regular turrets and stuff. I don't really have too great of an idea but I think it'd be super cool to have a clash for the Freljord. What do you guys think?
