I actually don't see this as a big challenge, if constructing from new. I would also suggest that a pellet pooper, especially one that has an internal firebox such as a Yoder, would simplify fire management to a very safe level. There used to be older pits that had counter balanced sliding doors, that slid up over the pit entry. This would be a high access option
