I suppose it depends on the sibling to a certain extent. Things would be way different if Azulon was around and Zuka was the only female in the family.
But if Azula is still Azula then Zuka would probably be more similar to Zuko than she would be otherwise. Ozai having two daughters would mean he has no male heirs, and would probably be incredibly hard on his first born as a result, to force her to meet his impossible expectations. Obviously this leads to the burning, banishment, supposedly impossible task of capturing the avatar, and so on.
So that parts pretty similar. The bit you can play with is in regards to femininity. Now, personally, I would imagine Zuka doesn't think about that a whole lot, and when she does, it's more in regards to her mother. But if you wanted you could tie that stuff in, especially by the time she and Iroh get to Ba Sing Se.
After a particularly dark moment, you could have Iroh cheer Zuka up by saying how she looks like Ursa- not to imply Zuka is worried about looks to any large extent, but again, more about the mother.
You could have similar beats play out in regards to the Jin situation, but instead, Zuka is a goodlooking waitress, who, like Zuko, let her hair grow out. Dude-Jin could be grossed out once he sees the scar beneath the bangs. Something like that.
All of this is to say:
TL;DR: They would be different, I mean they'd have to be, otherwise what's the point of the change- BUT, if you saw them side by side you'd go "oh. Yeah. Yeah that makes sense."
