Bones not keeping weights after Instantiate()?

Ok, so I create an object with an IDE defined mesh. I assign boneweights based on the position.x of each vertex.

Later, I instantiate the object, I then assign the boneweights to the mesh, however when I attempt to rotate the bones, they have nothing happens.

Here is the pertinent part of my project:

         DUMMYWALL = Instantiate(DUMMYWALL,World.position,Quaternion.identity)as Transform;
         Destroy(DUMMYWALL.gameObject.GetComponent<MeshRenderer>());
         DUMMYWALL.gameObject.AddComponent<SkinnedMeshRenderer>();
         //DUMMYWALL.localScale = Scale;
         Transform[] WallBones = new Transform[2];
         Matrix4x4[] WallBP = new Matrix4x4[2];
         MeshFilter WallMeshFilter = DUMMYWALL.gameObject.GetComponent<MeshFilter>();
         SkinnedMeshRenderer WallSMRenderer = DUMMYWALL.gameObject.GetComponent<SkinnedMeshRenderer>();
         Vector3[] WallVerts = WallMeshFilter.mesh.vertices;
         WallBW = new BoneWeight[WallVerts.Length];
         for (int i = 0; i < WallVerts.Length; i++) {
             WallBW[i].boneIndex0 = 0;
             WallBW[i].weight0 = Mathf.Abs(10*WallVerts[i].x);
             WallBW[i].boneIndex1 = 1;
             WallBW[i].weight1 = (1f - (10*Mathf.Abs(WallVerts[i].x)));
         }
         
         WallBones[0] = new GameObject("Bone 0").transform;
         WallBones[0].localPosition = WallVerts[189];
         WallBones[0].parent = DUMMYWALL;
         WallBP[0] = WallBones[0].worldToLocalMatrix * transform.localToWorldMatrix;
         
         WallBones[1] = new GameObject("Bone 1").transform;
         WallBones[1].localPosition = WallVerts[2];
         WallBones[1].parent = DUMMYWALL;
         WallBP[1] = WallBones[1].worldToLocalMatrix * transform.localToWorldMatrix;
         
         //Assign collections to DUMMYWALL
         WallMeshFilter.mesh.boneWeights = WallBW;
         WallMeshFilter.mesh.bindposes = WallBP;
         WallSMRenderer.sharedMesh = WallMeshFilter.mesh;
         WallSMRenderer.bones = WallBones;
 
         Transform southwall = (Transform)Instantiate(DUMMYWALL,(nCMfilter.mesh.vertices[0]*.99f),Quaternion.identity);
         southwall.name = "SouthWall";
         southwall.parent = nCGO.transform;
         southwall.localRotation = (Quaternion.LookRotation(Vector3.zero - southwall.transform.position) * away);
         MeshFilter SWMFilter = southwall.gameObject.GetComponent<MeshFilter>();
         SkinnedMeshRenderer SWSMRenderer = southwall.gameObject.GetComponent<SkinnedMeshRenderer>();
         Matrix4x4[] WallBP = new Matrix4x4[2];
         SWMFilter.mesh.boneWeights = WallBW;
         SWSMRenderer.sharedMesh = SWMFilter.mesh;
         SWSMRenderer.bones[0].localPosition = SWMFilter.mesh.vertices[189];
         SWSMRenderer.bones[1].localPosition = SWMFilter.mesh.vertices[2];
