Now that the idealogues are done bantering about their theories of the rise and fall of communism, capitalism, miniskirts, whatever...glad to see we're headed back to the question at hand.
Anyways, it may be hard to decide whether the replacement will be a good thing for Disney, or whatever the effect will be on Disney's finances, fame, fortunes, future, or flunkies, I'm assuming they aren't going to just replace Christopher outright. As it has been said, it is Christopher Robin's imaginery world. To transfer it to another child would be difficult, but not impossible. Though it would be impossible to not change the vision of the 100 Hundred Acre Woods slightly if we were to change the child.
But then again, how important is Christopher Robin to the stories? Even though his character is the "central" character, he is not the active character...he mainly acts as a "Deus ex Machina." My fear, then, is that when they bring in the girl, she will become more controlling of the story plotline than just a "helper" to the stories. My daughter is 2 1/2 and I can tell you she couldn't care less whether there is a Christopher Robin, a Chrissy Robin, or any Robin in the story, as long as there is Pooh, Eeyore, Piglet, and the rest of the animals. Even though we can argue about whether Christopher Robin, a boy, is necessary for the story, will the intended audience really care? You have to admit, Christopher Robin is a little "light" in dominant male characteristics, so I imagine Chrissy will probably be more tom-boyish than Christopher ever was.
I guess as long as they don't teach her to throw tantrums everytime she doesn't get her way, or other non-acceptable social behaviours, whose to say a girl can't have an imagination? Unless they're doing it just for political-correctness, then no.
