I did a quick test with the poses using Victoria 2. They work ok with some minor tweaking. V2 is definitely skinnier than V3 so if say the V3 pose has her hand touching her waist, the V2 pose will have a space and I had to twist the shoulder. For another pose, because for V2 the neck has two parts - neck and upper neck, the chin might enter the shoulder in some poses and will have to be tweaked. But I can say that other than these types of tweaks, the Poses look nice on V2 with a little more work.
