I doubt this would work for you, however in the case of my parents(mom is active, dad is not) I would listen to any personal advice they gave me and at the same time
I would let them know that the marital problem is between you and your husband and though any help from elders is appreciated it isn't necessary nor would it be
helpful. Like you already mentioned, I think at most, you could make a courtesy call to the local elder to inform of the situation. If the elder proceeds to offer advice,
merely thank him for his concern and let him know that it isn't necessary.
