Diffraction is not an issue, since the beam may split into pieces. Only: 
it does not matter.

Why? Well, the only direction of beam of relevance in this experiment is 
'forward', since the only measurement is at the end of the usual path 
(with the detector).

The beam would be widened, but not because of the rotation of the 
wheels, but because of the fine grid.

This wouldn't influence the measurement, since this is about the 
rotation and its influence. If a large part of the beam gets lost 
through diffraction, that is not important, as long it does not change 
with frequency of rotation.
