I'd urge some caution here though - going to more than two people will require some careful planning to allow for statements and rebuttals in a format that doesn't eventually die out to just two speakers or which drags on longer than your intended reading time.

I might point out fivethirtyeight's live blog as an example of how this can go wrong[1] - there is an unpredictability to discussion here which is partially covered by the fact that they are responding to live updates but suffers from the fact that discussion threads will suddenly die off.

1. One random example: https://fivethirtyeight.com/live-blog/biden-inauguration/

Yep, that's exactly why we haven't pursued something like this in the past... we're still sorting through the logistics!

Thanks for the link for an example of how not to do it!
