I think you misunderstand the problem. You can do that, yes. But have you ever moderated a diverse group of people? They're all very different. Some are bold and loud. Some aren't. Some are introverted or quiet. Or you somehow need to make them feel comfortable and safe before they speak up at all. Some say the first thing that comes to mind and they talk a lot, and some aren't even part of the conversation and you need to make them speak up at the right moment, effectively silencing the other people, because then you'll get their nuanced opinion and they used the time to really think it through.

I've managed some people in smaller groups over the time and I can tell you your approach just silences the interesting people. You won't end up with all opinions that way. And the result of the entire conversation just won't be great.
