My Standard Catalog of Firearms indicates the same prices for 12, 16, and 20 gauge Wingmasters. That being said, there would be a much smaller supply, and a much smaller market for the 16, so I would think if you can hook up with 16 gauge enthusiast, you might be able to ask a bit of a premium, especially if your Wingmaster is in good shape, and a bit upscale, say with checkering and a vent rib.
