A suggestion regarding height.

[Ditto]

Dragemons sounds ok to me.

The difference in Au Ra body mass is mentioned in their lore. It's a part of their race. SE isn't going to change all of that just so you can be an over-bloated disproportionate Au Ra female.

And as someone else has already pointed out, save for Au Ra, it's possible to have the genders fairly equal in height.

It isn't going to happen with Au Ra. It shouldn't, it doesn't need to, and it wont.

If you want to be a big husky female with horns, buy Ultima Horns and use them on a female Roe or highlander. I mean any race can have horns as a glamor now.
