Out of curiosity, what's the practical difference between shooting with a coated vs an uncoated lens?
This is not my area of expertise but coatings were introduced to reduce internal lens reflections and hence flare. They provide better contrast with both b&w and colour. With colour, the lower contrast with an uncoated lens results in lower saturation or more pastel looking results. This is why coated lenses are usually always preferred for colour work. With b&W, you can compensate in processing but have to be more on the look out for flare. (Many of the FSU coated lenses are highly regarded but still prone to flare.)
In regard to your earlier question about swapping shutter release assemblies, this could be possible by removing the top plate. The mushroom surround does not simply unscrew. However, you need a doner camera - individual parts are hard to find. The value of a hybrid will probably be reduced on resale and to what end? I understand that some Leica IIIs had mushroom surrounds, either as original or accessories, to improve the feel.
If the look is that important, go with an early 1f model and if the lens bothers you, buy a coated lens or maybe add a Jupiter 8 to try something a bit differnt but still in keeping with the style of the camera.
