Perfectly possible and more immediately cross-platform since it
would work with any platform that runs POV. I used a similar trick
a couple times for swapping the quadrants of an image as a step
in making images tilable. Just use the orthgraphic camera to avoid
perspective distortion and voila! The only caveat to observe is to
ensure you use no antialiasing and an image map interpolation type 
of zero to ensure the source images are not degraded by blending
or interpolation of any kind, but it should work quite easily.
