Actually this has been discussed before and basically you would be defeating the purpose of the beads. What will happen is that the beads will try to keep the humidity in the air constant but the humidor and smokes will likely keep absorbing and become over humidified. If you use the beads or something equivalent to them then just use the beads alone. You want to make sure you have enough for the volume, and as Grado mentions if the beads dry out too quickly then you might need to re-season your humidor.
