That would be something to behold. But Laurel better think of using a different wig for several of her costumes. Or Lois will guess that there's just one new superheroine around who uses a number of different aliases for different locations. That this girl would have to be her very own daughter doesn't necessarily have to occur to her, though.
On another note, this kind of scenario works best if you have a number of other superheroes around. Like Batman (and the Bat-family) and the rest of the gang. Otherwise, if Laurel is only the 2nd superhero around, things might get too obvious too soon.
Anyway, I'd love to read a story like that.
