Banning Items Instead of Champions? What do you think?

So i have been thinking about this for a while and have talked with some friends a couple of times but basically i wanted to get y'all opinions on this and what would you do if this was the case. So we all know about the banning phase and that before everyone selects their champion they ban a champion so that no one can play them right? Well what if you had the option to instead of banning a champion so no one could play them you could ban an item so no one could buy it during that game? You would have to decide on whether or not you wanna ban that champion that just tilts you whenever you just see them or ban an item that can make specific champions way overpowered. I think that could make champion select much more interesting. But the real question I wanna ask y'all isn't whether or not you think this should be a thing. My question is if this was a real thing do you guys think that you would find yourself banning more items over champions or would you just stick to banning champions? I'm really curious.
