A suggestion regarding height.

[CGMidlander]

The proportions will probably start to look off in the case of male vs female Au Ra if they were given the same height range. (Since height just adjusts the character size, but not proportions)

It probably wouldn't matter for most other races though, since the gender height gap is smaller.

This is probably the most valid of all objections to the OP's suggestion. Go in the char creator and play with the height slider a bit. Notice that it's not actually a height slider per se, it's a scale slider. Going up makes the character bigger in all dimensions--which means taller = wider too.
