In relation to that last anon's ask, do you think Brienne might and can inherit the title? Her father never remarried, might he already have decided to pass it on to Brienne or her husband? I think the Stormlands did strongly favor sons - then again Stannis wanted to crown his daughter. A coming and likely devastating war might work in her favor (needs must and so on).
Yes, I think whether or not Brienne gets married, she should inherit the title. She seems to believe Selwyn is still young enough to remarry and have a male heir from another woman, but deep down she’s aware that her family’s legacy rests upon her shoulders.
Re: the cultural bias against a female ruler, just like you said, "a coming and likely devastating war might work in her favor”. Westeros’ political and cultural landscape is going to change radically after (or even during) the war for the dawn. In the end we might have a queen in the North (Sansa), a queen of the Iron Islands (Asha), a “federal” queen of the Seven Kingdoms, or queen of the Crownlands or whatever remains of the current shape of the reign (Dany, if she survives), and whoever is left in charge in Dorne, be it Arianne or Sarella, will likely be a woman.
So I don’t think it’s a huge stretch at all for Brienne to become the next Evenstar.
