I’m not trying to build smokeless necessarily. Mostly, the rocks are for even heat distribution and appearance. I worry that the rings i bought won’t support flagstone, so it needs to look good without them

Honestly I’d leave it empty and cap the gap with pavers or similar. What it sounds like you are describing is how you build a smokeless fire pit and you’d want to avoid interrupting the airflow in that case.

This. Drill holes in the bottom of the outside ring and top of the inside ring. Though I’d recommend a much smaller gap if possible. If not possible, adding rock in such a way as to act as baffling would be good too. Metal louvers or ducting might work. The key is to get the air to heat up between the rings so when it exits the inner ring it burns quick and more completely.
