lod with animted hierarchy,question about lod implementation on animated hierarchy with animator

Hi. i was searching for some assets to make lod on animated characters, but i could not find any thing working on unity 2018.2. so i was thinking on write my own custom script to do that. the idea is basically replace every meshfilter mesh with the corresponding on other hierarchy (from the current lod level). i post the code so if somebody can tell me if this is a good idea or not.

 public class LOD_alex : MonoBehaviour
 {
 
     [System.Serializable]  // sin esto el array objetos no aparecerá en el inspector
     public struct _datosObjeto
     {
         public GameObject Plantillalod;
         [HideInInspector]
         public GameObject instantiatedLod;
         [Tooltip("no asignar. se asigna dinamicamente")]
         public float distancia;
     }
 
     public _datosObjeto[] lods;
 
     [System.Serializable]  // sin esto el array correspondencias no aparecerá en el inspector
     public struct _datosGizmos
     {
         public GameObject original;

     {
         m = Object.FindObjectOfType<manager>();  // through the manager we access the players camera (see update method below)
 
         // DEBEMOS INSTANCIAR CADA PLANTILLALOD Y PONERLA EN INSTANTIATEDLOD PARA USARLA DESPUES Y O ESTAR CREANDO INSTANCIAS A CADA MOMENTO
         for (int i=0;i<lods.Length; i++)

                 lods[i].instantiatedLod = Instantiate(lods[i].Plantillalod);
         }
     }
 
     // Use this for initialization
     void Start ()

         {
             if (sqrDist >= lods[i].distancia * lods[i].distancia && indiceLodActual!=i) // if the current lod is not the same that the lod to use, we change it
             {
                 // este es el lod que necesitamos colocar
                 reemplazarMeshLod(i);
                 indiceLodActual = i;
 
             }
         }
     }
 
     void reemplazarMeshLod(int indLod)
     {
         MeshFilter meshFilt=null;
         MeshFilter meshFilt2=null;
         for (int i=0;i<correspondencias.Length;i++)
         {
             meshFilt = correspondencias[i].original.GetComponentInChildren<MeshFilter>();
             if (i < lods[indLod].instantiatedLod.transform.childCount)
                 meshFilt2 = lods[indLod].instantiatedLod.transform.GetChild(i).GetComponent<MeshFilter>();
                 //meshFilt2=lods[indLod].instantiatedLod.transform.GetChild(i).GetComponentInChildren<MeshFilter>();
 
             if (meshFilt!=null && meshFilt2!=null)
             {
                 meshFilt.mesh = meshFilt2.mesh;
             }
         }

Thanks in advance and every suggestion will be very good received.
