Even though the Healing Guidance Prayer is in the LHP, would it be of value to retain that in any back-to-back DSMR sessions, so those intentions are preserved if the session is shifted in time, and are also preserved during repetitions of the session?

You are seeing now how good a feel you have for the necessary conditions because of built-in constraints and complexities. So, as you have seen and assumed to be so, a stand‑alone protocol is just that, capable of standing alone, so it must encompass everything including preliminary requests for protection right on through to the final wrap-up of instructions. So the protocol is fine as is and does not need to be trimmed. So your initial plan of doing a full LHP protocol and then a full DSMR protocol together on a monthly basis for subscribers to the Divine Life Support is a superb approach that will deliver on its promise. Any additional work will contribute further to the gains and the speed of attaining them.
