Basically, you're wondering if any Pinocchio-esque characters should pop up huh? By this I mean like the role he played and not characters made of wood turned into people xD

I guess then that would beg the question, did Melody go through the wardrobe alone? 

I think having someone who fills that role could be fun/

As for Yzma, I can see her and Zira getting along quite nicely xD but as I am not playing her, I can't speak for her lol. Jim and her could have crossed paths, though not in a good way
