That's very hard to make.
You need special software to edit the models.
First you have to change the places of female dwarf and male human mage,or to rename the two models.
But it's hard to do.
(He/she want's to change the models,so the other players in the server will see him/her character like a human male mage,but he/she will see his/her character like female dwarf).
Modding of client is dangerous and it requires time to learn how to make models,besides you can end up with not working client and bunch of crit. Errors.
