Kamala isn't meant to be The Muslim superhero, as there several Muslim heroes created before her (off the top of my head, Monet St. Croix and Sooraya Qadir "Dust" of the X-men, as well as Faiza Hussain, who wields Excalibur), she's just the one that Marvel really decided to focus on.
But more importantly, Kamala was never meant to be a sex bomb, she's 16. And forget the argument of "Oh, Oni can just age her up." No. That will not change the fact that the character Oni would be basing her on would still be underage in the majority of the world.
So no, no Kamala Khan.
