BG fix/override: Streamlined movement animations?

[Farmboy2003]

Difficult tehcnical question of an aesthetic nature, I don't know where else to ask.

in 'vanilla' NWN2 male and female PC models move about differently with different kind of weapon equipped. I am specifically thinking of greatweapons, greatswords, warmaces, greataxes, falchions etc.

Females and males run the same way with a greatweapon.
Females walk with the great weapon casually on their shoulder, males with it awkwardly held pommel at shoulder, very fallaciously.
Females sneak with a greatweapon laid low behind them almost scraping the ground, males sneak with a greatweapon the same way they run almost.

On BG these animations have been streamlined, so both models move about the same with a greatweapon - which is the more pleasing, female version. This is something that pleases me greatly. its a great thing in my enjoyment of the pretendy fun time of Nwn2, albeit small in the grander scheme of things.

How do you do it? Is it an override on nwvault that eludes my search-fu? Has some dev had the same level of frustration towards this small thing and made the changes him/herself? Is it knowledge that can be shared? With me? please?
