Without going through your specific situation, I can say that this is an 
easy problem.
Here are a couple of ways to do it.

a) use boost::variant

Make your functors: f, g, h
make a  variant boost::variant<f, g, h> v;

v = f or g or h ...

#include boost/serialization/variant.hpp
serialize v

b) make your functors f, g, h all derived from a base class - functors
make the base class polymorphic by making at least one member virtual
EXPORT f, g, and h

functor *fx;
fx = &f, or &g, or &h

serialize fx

c) There might be a way to do it with boost::any also.
