That's why I'm saying go neutral. At least it's better than fixed character walks.
But men don't walk or run like women in general. There's a necessary segregation when it comes to physical aspects. It's just how it is.
Female Shepard essentially uses the average male "style" of walking, so you could technically just translate this into DA and just name it a "gender-neutral" animation.
However, this is much harder to do that it sounds as the different races have different skeletal structures and therefore require different animations. (In Mass Effect, all humanoids followed the "male" human animations with the Asari being a notable exception with their female Hawke-like struts)
As you can see from that "female elf walking next to Cassandra", giving the elf the "gender-neutral"/male walk made her look a little weird, while I'm sure the bulkier humans and tall Qunari would actually look relatively OK in comparison.
This means that you'd have to tweak each set of animations for each race, and then make sure that every cinematic in the game complies.
This is a whole lot of extra work that I'm not sure they had enough time for. If you add all the other "small changes" that people are asking for in this forum, you'd require at least a few more months in development.
Perhaps in the next DA game, they'll have more time for such relatively low-priority intricacies. After all, they will most likely have less work on engine upgrading and more time on actual game content development.
