Idea for Alternate Universe of Nora

I do know if this is already been made but my idea is that the role between Victor Freeze and Nora have switched places. Victor Freeze catches the terminal illness that Nora was meant to get and Nora becomes Mrs. Freeze.

I imagine that instead of wearing a suit, she had something happen to her to make her body into ice. Having the power to manipulate ice around her, change the temperature around her, and as well as Mr. Freezes powers like not being able to age.

Feel free to let me know about this idea.
