I use T6M Equipment Replacer NV by Izumiko. This mod adapts most of the vanilla outfits to the new woman body, included power armors.
Otherwise, I really wanted to change the footstep sound of every power armors in FNV. I met an unexpected problem though.
Whatever sound mod I use, the T6M Equipment Replacer mod is just ignored. In other words, when I load the last mods together, I have a female power armor which has actually new footstep sounds but which is identical to the male power armor, while Mod Organizer doesn't notice any incompability.
I tested many combinations but I haven't found a solution yet. If someone has an idea, please talk to me.
