Most poses are made for individual purposes, they're made for custom settings of the makers. I myself use such settings, most regular poses don't work on my set up. You change some fairly minor things, like hips, legs, etc...and yeah, pose doesn't work properly anymore either. I also use a tall male with smaller females (just works way better for poses, male & females of the same game height, the females are actually taller and seemingly a bit larger too)
I basically need to use the same base settings in some body parts for all my models to use my own poses, essentially I know what I can and can't change.
YOu can either adapt the poses like some of us do, or find the proper settings.
