I would go ahead and take to a consistent 200*-205* and really probe tender then wrap it in BP and/or foil, put it in a good tight cooler or cambro hot and fill the void with towels or crumpled newspaper; it will keep just fine. Your bark might suffer, but the meat will stay hot-to-warm and moist. Just me $0.02, good luck.
