When I said "three degrees of freedom" - I didn't mean "X-Y-Z", I mean't X, Y and Rotation-about-Z.
Whilst (in theory) a Killough platform moves in X and Y only - they do rotate a little in practice.

From reading the specifications for the mouse chip, I get the impression that the magnification
has to be quite precise in order for it to work. I'd be very suprised if something as simple as
sticking any old lens beneath it would work.
