How can I change/set keys in an animation clip through code?

I'm using sprites to animate a game object, but I also need to change these sprites (or its original Texture2D) at runtime. The reason is, each part of the game object has its own Sprite Renderer (and its own set of 12 sliced sprites in its main Texture2D), and I want to let the player choose the sprite they want for each part, without affecting the animation. I'll also need to create different animation clips based on the sprites the player chooses.

Is there a way to achieve this via code or feature?
