First of all, have you already try to do it? In some cases the 
derivation is fine. Can you provide a minimal example showing an
error message?

The official method to use a custom Point type is to defined your own
kernel as described here:
http://www.cgal.org/Manual/latest/doc_html/cgal_manual/Kernel_23/Chapter_main.html#Subsection_11.5.2

If you do this then all functors defined for CGAL kernels will works
with your point type.

Unfortunately not now, but that may change in the future.
