I think the idea of constantly having that many cards banned from Wild kind of defeats the purpose of the game mode. Bans should be used sparingly against cards that break the game mode and create unfun/uninteractive gameplay. It sounds like you want an entirely different experience than what has been offered since Wild was introduced.

I think this idea would be a lot more acceptable if this was introduced in Standard and Wild but as separate game modes. Ranked, Ranked Rotation or something, and Casual. At that point though, there may be too many options and it may become a little too convoluted. 

On a sidenote, I really would like a 3rd game mode where it consists of the Core Set and 3-4 random sets. We had a tavern brawl a few years ago that basically tested this, but we haven't seen anything like it since. That would definitely be a breath of fresh air in my opinion.
