I don't think the character is that different, she's still the team player who prefers to use words, not brawn, to solve conflicts. How she's drawn certainly is though, as Ewing's books depicted her with longer hair (bobbed instead of cropped). Incidentally, it wouldn't surprise me if any new SG solo changed her hair to the much longer Rising hairstyle. Doreen's canonically seen what that looks like thanks to her AU twin, and she liked it.
