I don't think it'll work. You might get extremely lucky and find some pair of lenses that are close enough, but I would not risk a lot of money on it. Here's one example, the M and A 50mm f1.7s:
The aperture mechanism that you can partly see on the right is upside down and concealed on the left. Not even the five chrome mount screws are the same. I'd say except for the elements, these two have no common parts, and I'm not sure about the elements. If you had a late M design, maybe, like a late M50/2 built in Taiwan - but you wouldn't gain much in construction, since those lenses had already started using more plastic.
