JK may be a transphobe but this community doesn't belong to her anymore anyway.
Imagine a fic where Kara and Alex got into Hogwarts. Alex tries to help her little sister out when she but just can't always be there, especially in classes.
When they're learning wingardium leviosa Kara just can't get it so she does something else instead. Lena looks over at the girl and wonders why she's kind of sweating and out of breath. Turns out Kara had been running back and forth just putting the feather higher in the air when it falls. She'll practice later with Alex anyway.
Being the little shits they are Alex wants to impress all her friends, the spell isn't suppose to work on people. Still, with a simple action and saying, Kara is hovering off the ground and Alex's friends are going mad.
It isn't until Lena walks past and sees that girl in her year floating that things finally cool off as she steals Kara.
A little while later Kara saves Lena from a dementor attack, Lena confused because they hadn't learnt that yet. When she looks over Kara is just using the eye lasers.
Just generally Kara using her powers at Hogwarts and the Danvers sisters being little shits. Their head teacher knows but thoroughly enjoys hearing the confused teachers talking. His favourite story was when Alex made instant ice cream by 'giving' her sister freeze breath. They made a killing over the summer.
