As far as I know, the "cute" Stonebreaker females (Karyuu FTW!) are already able to sit.
And most players of female Klyros already know that thes should add a note into their character descriptions (and indeed, "Tanner" and "Eckar" don't sound female). So next time you meet an unknown Klyros, "look at" them! (Right-click or "/targetinfo"), they might tell you what you can hardly see.
