My folks live in the PNW and they have a pellet stove, which is quite common out there for winter use (cool, damp winters). It works great and pellets are readily available most anywhere for a good price. Their's also has an auto-feeder with a large hopper. Start the fire, set the feeder to whichever speed you want (faster = more heat) and forget it. You also don't have to worry about finding firewood, and also the legalities of transporting firewood due to emerald ash borer.
You should have little problem finding a wood-burning stove insert for your WBFP. They are quite common. While in HS my folks traded our neighbor our WBFP for their WB stove insert. Both were a direct fit. The insert worked fairly well, but I think the free-standing units are the way to go.
My house has a free standing wood burning stove (buck stove) and it will heat you right out of the house it gets so hot. Due to emerald ash borer and the fines for transporting firewood I'm not sure how much the pile that came with the house will last. State fines are $4K and federal fines are higher, although I'm unsure how much. I just checked federal fines are up to $250K and/or imprisonment. KS is not a quarantine state, but for those in MI, OH, IL, IN, PA, MD, be aware.
