Yes, it is possible. Humidipaks (or the equivalent Boveda?)can be purchased in different RH amounts, yours could be 45? I have extended the life of packs in the past by using an oasis soundhole humidifier, either not depleting the humidipak as quickly or maybe actually recharging a little bit.
In any case, a 214 will be quite happy with 45%, and just keeping it humidified to any consistent level(in the safe range) will allow for a setup that works wherever the woods will settle at that level.
Now I look back on my late teens and 20’s and wonder how my guitars survived with no humidifiers in Maine, but they did.
I bet that 214 is bringing great joy to you and your coworkers, what a great idea.
