Programmatically Swap All Sprites In An Animation

Right now I am using the LateUpdate Method and swapping the sprite depending on what sprite it is. For example when the character is running the helmet object swaps its sprite from Helmet1_1 to Helmet1_6 over the course of the animation. Now what my code does is it looks for what sprite you would like it to show instead, for example Helmet2_1 instead of Helmet1_1 and over the course of the animation it'll swap the Helmet1_1 for Helmet 2_1 and one second later Helmet1_2 for Helmet2_2. Is there a way to set all sprites within an animation until changed programmtically?

Code (CSharp):

1.         foreach (var renderer in Breastplate.GetComponentsInChildren<SpriteRenderer>())
2.         {
3.             string spriteName = renderer.sprite.name;
4.             var newSprite = Array.Find(subBreastplateSprites, item => item.name == spriteName);
5.             if (newSprite)
6.                 renderer.sprite = newSprite;
7.         }
