That won't achieve much. The temperature inside the bag will stabilise at the same as outside. Insulation doesn't generate heat, it simply reduces the rate of transfer.
Your slants will be fine at anything above freezing. The cold of the fridge reduces the activity of the yeast cells and causes them to go dormant.
