I assume...you mean make non-BodySlide meshes be changed by BodySlide? Can't happen as things stand.
Have a look inside CalienteTools/BodySlide/ShapeData/CalArmorForsworn. See all those files? You need to make all of those for each mesh you wish to include in BodySlide. It's a lot of files, and quite a lot of work, which is why Caliente has been spending so much time working on them, fixing the weights and any clipping...and everything else. =) She has offered to help out those who want to make their mods BodySlide compatible, though, so you could always send those modders a message about wanting their armours/clothes compatible.
Edit: Ninja'd by Caliente!
