I hate to be a wise guy, but honestly, the answer is to NOT USE WA lenses
that would get into this problem area......  For Normal and 75/90 or 135
lenses this is still an option.....

For the record, does anyone know the maximum angle of the rays that can be
acceptable?  From that and the body mount to FP distance we can pretty
easily figure out which lenses would be OK.......

There are large technical problems with the conversion. Leica lenses,
especially the wide ones, are designed so the rear element is very close to
the film plane. As a result many rays strike the film plane at very shallow
angles.
