Your idea is basically the same as specifying a clone allocator.  The
only difference is that the clone allocator needs to know how to
allocate objects, not just deallocate them, since you can
v.push_back(4) into a ptr_vector<int> v.  SFINAE means that you might
even be able to get away with only the deallocator, at the cost of a
(possibly severely) reduced interface.
