I wouldn't say never. She's a popular enough character and the MCU could use more female heroes. Probably wouldn't get her own movie, but she'd still make for a great supporting character. (Though, I'd still cross my fingers for a nonsensical courtroom drama.)

Only issues I see are setting up her existence in the universe they have and actually being able to create the character without her looking like an uncanny CG mess.

Drawings like these make me want She Hulk in the MCU.
But it's not gonna happen.
