I'm trying to make a combination armor (like so many I've seen on nexus ect.)

However... I dunno if I'm doing something wrong, or if Nifskope cannot do it alone...

If someone could help me out, it'd be much appreciated.
Either instructions on how to combine this armor without it crashing the game, or if someone with the skill would be willing to combine it for me.
