Of course :-) What I did was this:

template<class Derived, class Base>
BOOST_DLLEXPORT const void * void_cast_register(
     const Derived * /* dnull = NULL */,
     const Base * /* bnull = NULL */
){
     boost::python::detail::force_instantiate(
         void_cast_detail::void_caster_primitive<
             const Derived,
             const Base
         >::instance);
     return & void_cast_detail::void_caster_primitive<
         const Derived,
         const Base
     >::instance;
}
