Don't do that. Give them 2 hours in the smoker at whatever temperature you can get it up to and then foil them and place them in the oven at about 300 F for a further 2 hours. Check for pull back and if they need longer give them another hour at about 250 F (checking them after 30 minutes).At this rate we might be ordering pizza!!
They will be picking up the smoke flavour while they are in the smoker so they will still taste good.
