I love thinking about how things could be different if they were genderbent. It was something I loved in fandom too (before the whole "hdu it's offensive to trans people" thing). For instance the different designs. I was never a fan of give them huge boobs, a short skirt and long hair and tadah! Or the other way around. Like there's no consideration there. But when it's actually given some thought it's a lot of fun to think about how the designs would change it can be really good. And in worlds where there's an actual difference between how men and women are treated.
In my world, women generally have the magic, men with magic are weird. So it'd actually change quite a lot for quite a few of them. Percy, for instance, who's already have a very sheltered life by the standard of his peers, put down to him being an only child (something highly unusual in this world), would probably be reduced to Rapunzel level coddling with only mildly better intentions.
