Some years ago I decided to fill one pose mod with only my favs and take that with me. I admit, it's not exactly rocket science to move poses from one mod to another, especially if you already modded a bit, but I'll list some things here that made this easier for me - as well as an edited CTAddPose esp to help with it.
I fell in love with some of the hairs my characters used in other Bethesda games and I wanted to grab them from Skyrim and Morrowind. Here's how I took Skyrim hair and made it work in Oblivion. I recorded a video of it, but since there is no explanation (I hate talking), there is a step by step description.
