I'm not sure about all cameras, but I had a shutter go bad on my First Six camera. And I put a German Pronto shutter in it and the lens fit perfectly. So it is possible, but I'm sure you would have to check your specific camera, lens, and shutter.
So why would I do that? I did it because the lens is a wonderfully flawed lens. I just couldn't part with it.
