New Juggernaut/Tank Idea?

I want to try and see if we or Riot could create/add a champ similar to the Behemoth from Horizon Zero Dawn. I especially like the parts where Behemoth uses its weight to attack, the anti-gravity device and also the electric seismic shock head slam that it can do (those that played Horizon Zero Dawn will know what I am talking about). I think that the anti-gravity concept, seismic slam attack and the momentum attack could be an interesting kit.

Maybe like for the anti-gravity thing, it is an AOE field that suspends enemies caught in it. They can’t auto attack but they can use non moment basic abilities (not those that enhance AAs). While suspended the enemies can’t be affected by crowd control but they can be damaged. Rough idea and I am really open to alternative ideas/concepts. I would also be happy to instead put the anti-gravity ability to a basic spell and have the character/Behemoth just throw something like terrain, a boulder or a couple of rocks, or even enemies.

For reference here is the Horizon Zero Dawn Wikia page on it and you can also look up videos in Youtube for in game examples: http://horizonzerodawn.wikia.com/wiki/Behemoth?li_source=LI&li_medium=wikia-footer-wiki-rec
