So this is starting to go off topic, I want to ground it in this:
Making model variations is time consuming. Assuming we can only choose one, how do we reconcile two contrary perspectives that appear to be mutually exclusive?
Well that's a tough one especially since I think there are more than two contradictory perspectives on the matter... everyone you ask will have a different idea of what they want to see or at least variations from each other. Human nature and all
My 2 cents for what it's worth (probably not even 2 cents) and strictly my own opinion:
I actually think you're helped by having four races though because each race already lends itself to differences in how they look, qunari tall and hopefully broad, dwarf short and stocky, elf lithe and slim and human athletic and... something. Hopefully that's at least giving you four different models to start with and what the discussion seems to be about now is the clothes and armour being worn from there.
In terms of armour and clothing options I'd say it starts with the setting for me and equality between the genders so if men have full plate women have full plate and if women have the chainmail bikini men have the chainmail bikini as well. In an era of swords and bows before gunpowder is really a thing then practical armour makes sense setting wise and I'd like that for mages too but that could be because I don't like dresses and want to wear pants Damn It! 
But now we're back to personal taste so the more options the merrier as long as what's good for one gender is good for the other. And yes that means I'm fine with dresses for both men and women and suits for both men and women as well. 
Or have I missed the point and what you meant by model variations? If so please ignore.
