I've taken apart a good few lenses over the years and in my experience a sock-it-and-see attempt is VERY unlikely to work. In modern lenses there are just too may 'tricks' to get past the internal construction. Can be fun to try (if you're that way inclined), but I wouldn't expect a working lens at the end.
