A couple of points - female superheros are going to be built like athletes, not supermodels. Also armour, including plate, did not hinder one's movements. It was speciically designed to spread it's weight evenly across the body. The convept that it was so heavy knights needed to be winched into their horses is nonsense, a Victorian myth. I've seen people do stunt riding on horses in plate, plus do jumping jacks and cartwheels. The main disadvatage was exhaustion, because it was heavy, and that the visor cut of your peripheral vision. Also, waring a gambeson underneath mail was essential, since obviously metal armour is going to heat up quickly, even on mild day, Also, it was quiet. You can jump up and down in a hauberk or byrnie and no one would know you were wearing it.
