While I know very little about editing meshes but I've toyed with the GDAs a bit and I foresee an issue with scaling. If we only change the height dimension and not the others then we may get distortion. Kind of like when you watch a full screen movie on a wide screen. When standing, the elf will look normal. But when running or fighting or doing anything more active than walking, certain body parts will actually look too short. Just a possibility to look out for.
