Replace GameObject Children with For loop and foreach loop missing objects

I'm just trying to make a simple remove and replace with a new gameobject that is a child of a child in a selected gameobject for a editor tool. However, it's literally missing gameobjects. If the child has 2 gameobjects. it's only change number one. if it's got 4, then it'll only change 2 and 4.

        void Update(){
             gameObjs = Selection.transforms;
             if(_canReplace){
                 Replace2();
             }
         }
 
         void Replace(){
             foreach(Transform gameObj in gameObjs){
                 foreach(Transform FirstLayer in gameObj){
                     if(FirstLayer.gameObject.name == "Item" || FirstLayer.gameObject.name == "Colliders"){
                         continue;
                     }else{
                         int times = 1;
                         foreach(Transform SecondLayer in FirstLayer){
                             GameObject got = new GameObject(times.ToString());
                             got.transform.SetParent (SecondLayer.parent);
                             got.transform.position = SecondLayer.transform.position;
                             got.transform.rotation = SecondLayer.transform.rotation;
                         
                             DestroyImmediate (SecondLayer.gameObject);
                             times++;
                         }
                     }
                 }
             }
             _canReplace = false;
         }

I've hear somethings on the web to try not to use foreach loops But...

 void Replace2(){
             for(int i = 0; i < gameObjs.Length; i++){
                 for(int j = 0; j < gameObjs[i].childCount; j++){
                     if(gameObjs[i].GetChild(j).gameObject.name == "Item" || gameObjs[i].GetChild(j).gameObject.name == "Colliders"){
                         continue;
                     }else{
                         int times = 1;
 
                         for(int g = 0; g < gameObjs[i].GetChild(j).childCount; g++){
                             GameObject got = new GameObject(times.ToString());
                             got.transform.position = gameObjs[i].GetChild(j).GetChild(g).transform.position;
                             got.transform.rotation = gameObjs[i].GetChild(j).GetChild(g).transform.rotation;
                             got.transform.SetParent (gameObjs[i].GetChild(j).GetChild(g).parent);
                             Debug.Log (gameObjs[i].GetChild(j).GetChild(g).name);
                             DestroyImmediate (gameObjs[i].GetChild(j).GetChild(g).gameObject);
                             times++;
 
                         }
                     }
                 }
             }
             _canReplace = false;
         }

This has the same exact problem. Anyone know why? Thanks
