Mathematically speaking, isn't it true you can compute the coordinate transformation (with your choice of map projection, perhaps ignoring the poles)? The real problem is that your metric / notion of distance has changed, so you can't simply compute distance as sqrt((x2-x1)^2 + (y2-y1)^2) and expect it to map neatly to a circle on the globe.
