it is (sort of) possible. I'm experimenting with the skintone changers myself, and I know for a fact it is possible to use two meshes toegther with it, if you count the "naked" mesh (only available when bathing/diaper changing the baby OR with the wardrobe adjuster in the insim mod). So technically you can use an invisible version of the other mesh, together with the "nude" mesh. The textures has to be on the skintones of the skintone changer. I've done it myself, so I know it works
