Is it possible in C++ to create a dynamic mimic class that can mimic another class more than once?

Question

C++ / C#

On the example of the game:
There are two classes "Vampire" and "Elf" with their own parameters and methods. And there is the Mimic class , which, when creating an object, does not have a rigid binding to some other class, but during the game it can temporarily turn into a character of another class and get its capabilities .
Is it possible to implement this with C++ classes? (Given that the implementation of all other classes can be tailored just for this purpose.) . Is it possible to make such a binding at least once during the lifetime of an object?
Options through crutches are also of interest.

Answer 1

Use a strategy object or delegate objects.
The point is that the class implements its methods through similar delegate methods.

Answer 2

class MimicBase{};
    class Vampire : public MimicBase{
    public:
        Vampire();
        Vampire(MimicBase& m) : MimicBase(m){};
    };
    class Elf : public MimicBase{
    public:
        Elf();
        Elf(MimicBase& m) : MimicBase(m){};
    };

    MimicBase m1;
    Vampire v1(m1);
    MimicBase m2(v1); //Обратно

The bottom line is that when initializing a class object, for example, Vampire, you take control of the call of the constructor chain and can substitute the parent object
