Remembering the inspector from the FSDO who was a former helicopter mechanic and had an eye for cotter pins, I dont think he would notice the missing washer. I think I would simply omit the washer. As you say, torquing the bolt is a non issue given that it is in shear only. I suspect you could get away with a clevis pin, washer and cotter pin.
