I don't like the underlying sexims either. The reasoning is that boys don't want to see movies with a woman's name in the title, because they think it must be 'too girly', so let's change it. Would Disney ever consider changing a movie title with a man's name in it so that girls won't think 'Hey this movie is only for boys, I don't want to see this?"
So, just as a thought-experiment, instead of reference to a man in the title,let's make it refer to the girl or 'gender-neutral' and confusing at the same time:
Aladdin : Princess Yasmin and the streetboy/The (mystery of the magic) lamp
Hercules: Meg's sacrifice/Gods and mortals
Tarzan: Jane and the jungle prince/ The Gorilla kingdom
