Slight armor mod conversion

[ErikModi]

So, there are two great skimpy armor mods I really like.  One of them is more complete and supports Bodyslide 2, the other has (I think) some better armor models, but doesn't include anything from the expansions and is not Bodyslide 2 compatible.  I'd really like to get one part of one of the previous armor sets imported on the new one, but I can't seem to get it to work.  Specifically, I want to take the Dragonscale "bra" from http://www.nexusmods.com/skyrim/mods/13004/? (that has my Dragonborn almost falling out of her top), and replace the Dragonscale bra from http://www.nexusmods.com/skyrim/mods/25259/?, so it'll conform to my Dragonborn's custom body and I can still look down her top.  I've tried copy/pasting the armor part I want in Nifscope, but that doesn't seem to add the Bodyslide 2 compatibility, even when I only copy the mesh for the part I want.  Any suggestions?
