I had a similar idea, except using Boveda packets instead of beads. My idea was to use a traditional humidifier to add the bulk of the humidification and let the Boveda packets act as the regulation, adding or removing RH as needed. The risk is your Boveda (or beads) becoming saturated if your main humidification device is adding that much excessive RH. The only real advantage I could see would be needing fewer Boveda packs (or beads) for a given size humidor.
