You do not even need to use boost. You can simply use a functor( overload () operator) as a base class and inherit from it for every different function you need.

It is possible by using something like Boost.Any or Boost.Variant. Keep in mind, however, that you will have to remember somehow what the signature of the function stored (hidden) inside the boost::any object is, so you can retrieve it.
