Hopefully you will look at this in a balanced way... look at how negative stereotypes of men are reinforced as well as negative stereotypes of women. For example is still very difficult for men to be seen as good parents, these stereotypes hurt fathers. The trendy thing now is to emphasize positive traits of women and negative traits of men. This would disappointing in any educational exercise about gender stereotypes.
As far as Cinderella, please resist the temptation to feminize the male characters. That would defeat the purpose off the story.
Cinderella, the hero of the story, should be masculine, rugged and handsome. The Godfather (who gives the hero of the story his fancy suit) should also be masculine, nurturing and magical (men rarely get to be magical in these stories)
In the original Cinderella, the prince has always been given short shrift. He never came across as a noble or strong character, he is often portrayed as vain buffoon. I think this would be an interesting character to see portrayed with traditionally female traits.
