I get what OP is coming from because I'd buy fantasia's just to have a pick at better designed races & updated character options that have nothing to do with height.
Or I'd mention how I'd buy Hilda's ponytail off of the mogstation & even though Yoshi-P has said he'd add it if people show interest back several years ago which people have constantly & we still don't have it- and those are just hairstyles people have requested- All we've gotten are several lacking hairstyles from a contest that was botched & medium length hair from the dancer quest due to the complaints of us only having short hair-- People have asked for WoL stubble & beards only to be told "no."

Updating only the height is an even longer shot & people would want more than just a new height adjustment, so goodluck on your requests
