I've used such a technique for years — inverted luminosity mask of a "null frame" shot.I've struggled with the vignetting tools… Below is the Olympus 75mm lens from f/1.8 to f/22 off a white card.
You need to "normalize" it by adjusting the curve so the darkest spot is 100% clear, and use it in "luminosity" blend mode, so it won't darken your entire image.
For example, I stitched 13 images to make this panorama. The problem is that I had horrible vertical banding, due to lens vignetting, which got progressively worse when two edges were overlapped.

So I made an inverted luminosity mask that nearly totally eliminated the banding, to the point where I could print it 120" wide, to hang as a banner in our art festival booth. (I also disproportionally scaled it by about 5:1.)
