Can one measure parts with unusual or complex geometries?
Yes. Because you can calculate the calibration coefficients using a fairly simple elastic finite element model, geometric complexity is not a problem. A paper by Rankin et al. (reference) has a good explanation of FEM calculations of the calibration coefficients. The other consideration for complex geometries is that you have to be able to assume that on the plane of the cut. the stresses only vary with cut depth, not in the transverse direction. If the stresses vary in both directions of the plane of the cut, then consider using the contour method.
