A retelling of Thumbelina?

Both girls can be described as small, Thumbelina literally and Jupiter by her low social standing. Both are born under unusual (and in a way magical) circumstances. They are raised by a single mother and live simple lives. Both girls are then kidnapped from their homeworld by a family of threee siblings and a mother (in one case the mom is dead). The oldest sibling is the storys most brutal character and the main villain. Several charaters wants to "own" the girls for their own selfish reasons. Both girls fall in love with a man with wings but the man is later belived to have died only to return later. But before he does both girls are almost tricked into marrying someone they shouldn't. In the end the main villain falls to his death after fighting the heroes. One girl becomes a fairy princess and the other a galactic queen. They return to their homeworlds with their newfound love. The girls gains wings/rocket boots of their own and the happy couples flies of into the sunset. Both girls are also total air heads and extremmly gullible.
