Things we learned in Leia: Princess of Alderaan:

1) Leia actually dislikes the elaborate hairstyles but wears them to honor Alderaan, and would go around in a ponytail if she had the choice.

2) Alderaan braiding customs apply to the heir to the throne regardless of gender.

So in any given twin swap au where Leia goes to Tatooine and Luke to Alderaan, Leia would be in practical, probably short hair while Luke has the long elaborate space hair.
