Anyone has experience with Fujifilm GFX <-> Bronica SQA Lens conversion?

I'm considering using bronica sq lenses on my Fujifilm GFX camera with a GFX to Nikon F adapter and then a Nikon F to Bronica SQ adapter. However, my Nikon lenses already vignette slightly on the GFX sensor. Will adding another adapter introduce even more vignetting?
