It's kind of stupid to call it a gender swap. All the Links are different, and they're only even consistently called "Link" as a reference point since you name your player. In Wind Waker you are just a descendant, so what stops a descendant from being female? That's the exact, EXACT same thing as it being a "new" character. Now if they're going to make the character design super similar whatever.
But an Impa backstory game? Sure why not. Or some Zelda-focused game. But I feel like those would tend to (hopefully) play a lot differently than the standard of a swordsman.
For the record I don't think the new game will have female Link.
