It's hard for me to speculate on that. It would really depend on how the committee would want to structure that. Members might want the set-up a bit like the House is set up, with chairs on either side, with maybe a central podium, or members could rise and speak from their assigned seat.
There are a lot of different possible ways it could be done, from rather informal to rather formal.
The place I referred to is the parallel chamber in Australia, which is in a room not unlike this one, set up for that purpose in a committee style.
