Can a request be included in the Lightworker Healing Protocol to have the Protocol be implemented by the divine realm every other day, in perpetuity, through not only the present life but all future incarnations?

This can be done and, in fact, would serve to maximize the benefit of the work. Even though this involves a vast span of time potentially, there would not be a dilution of the intention because the way the divine realm always works is to trace back a request to its origin and determine the intention in place when the request is initiated. So each time the Protocol is implemented, that would be the driving force and would never be depleted because the intention is for the repeated application in perpetuity, and all of the force behind the requests would still be there and referenced as an instruction and would cover the continued application indefinitely. This is an excellent idea because this reduces the need for widespread awareness of this optimal healing modality because, once done, the person will be tended to as long as there are humans in the earth plane needing assistance to prepare for their eventual ascension.
