I don't think it would be difficult at all.  In fact, think of what Ruby has 
to go through when you make a class into a singleton with:

obj<<class
end

It has to pull forward all the methods of the object's class into a new 
anonymous singleton class for the object.  That's a lot more work than simply 
pointing the object's class to a different class that's already defined with 
all of its methods and such.

It should be very easy to do.  I'm wondering if a C extension could possibly 
even do this.
