I would assume that the resulting reduced slides would sharper,
proportional to the reduction.  I don't know where I would run into
the physical limitations of the film grain.  Any experience?  Any
guesses?
Film grain is not the problem, ligh wrapping around the sharp edge of the image is.
There must be a duplicating film made for slides.  Any suggestions? I
assume is would be e-6.
Kodak makes a Ekta Slide Dup Film 5071, you can get it in a 100' roll and 36 exposure roll. It also comes in 100' 70mm film.
One last question.  Will I have any problem with depth geometry?  I
would think the on-film deviation would scale proportionally.
Nope
Why 5 perf?  I'm thinking of preparing a slide show for
non-enthusiasts.  I don't think they will care about or notice super
sharpness, certainly not enough to warrant fooling with MF
projection.  Simple setup and transport is my aim with 5 perf.
Still, I don't want them to look like crap, either.  :^)

An alternative is to shoot everything twice, once with a Realist,
once with the Sputnik.  This would eliminate the need for
duplication.  But it would mean copies of everything I shoot.  (With
duplication, I would copy just the good ones.)
Any in camera images, is always sharper then a dup. unless you go into the very expense duplicating system.
Any thoughts?  Experience?
My 2 cents worth.
