I disagree; they seemed to integrate both Kotone and Gold into HGSS without "completely transforming" the original GS template - there were only minor alterations. I think they could have added Leaf into the storyline of FRLG quite easily without changing too much. They simply didn't think about it, or chose not to.

"Canon" or not, she's still an awesome character. And there's always fanfiction/art
