I think she will.
I don't think Tim wanted her just to redesign stores. But also, to be a "face" of Apple.
If Apple brought back the, "Im a Mac.", "I'm a PC." commercials, and Apple wanted one of the two actors to be female, which of the two do you think they'd use for female? There's no way they'd use a female for PC.
Angela helps to smash the idea that "computer stuff" is for nerdy males. But that only works if you put her out there. If they don't see and hear her, Apple loses tremendous marketing value.
She helps shape Apple's image.
When she talks, and there's lots of youtube videos, she sounds like Steve Jobs and Jony Ive combined.
The Ted Talk was done after getting hired by Apple. Keep that in mind. She starts by saying she's nervous, that presentations is not her strong suit, (I'm paraphrasing), but then as he does as good or better than most that Apple has on stage.
Watch her at TED and imagine her on Stage for Apple - when the world is so used to every single person up there over the years has been male, and white (Beats fixed half that equation).
Also note, that when she tells a bit about herself, she doesn't say she's been in retail all these years, but rather, she's been in the fashion industry for most of her life. That's how she sees herself, and that's how Apple sees her - not in charge of "retail."
Listen to this talk, and then think of Apple showing people using the Watch to send their heart beat to a loved one.
