I'm not familiar with that lens. Did it come with the focusing helicoid and cone? If you have the ground glass back, you can check to see how it covers through the clipped corners. I suspect it will cover fine, but you won't be able to shift the lens like you could with the Grandagon 55mm (image circle 163mm).
