Problem changing Armor Slot

[Schottenschaf]

Hi !
i stumpled across the " Synth Combat Armor by Xz CJ zX" mod lately and have thought :
Could be cool if i could wear a Raider Chest piece AND my Heavy Metal Armor at the same Time

so the Pipes would come out of the Metal Armor

 

so i fired up FO4edit the first time created an empty .esp

copied through override all the Raider Armor Pieces from "Armor Addon" and the one from " Armor in my .esp file and editet the line from Torso (41) to 56

but it doesent work

 

then i tryed to edit only the Heavy Metal Armor because so i had only to edit the Metal armor part from ARMOR and the one from ARMOR ADDON = Heavy metal armor

tryed differnt slots not only 56

 

but nothing seems to work ingame. My character changes the Armors and not equip both

 

First time i tried to mod something like that so i think i missed something

or is it simply not possible ? Dont know

 

perhapse someone can help me here in the Froum :)

Thx

(sry for bad english :D )
