Blend textures with SpriteRenderer

I have 2 atlas (exactly the same packing but with different texture).

And for each sprite, I need 2 part, 1 background and 1 foreground. And I need to add the foreground to the background.

It's possible to do that without creating 2 different game objects?

My other option is to use a 3D Mesh Renderer. But I'll to do more stuff manually.

 

You'd need a modified shader with two textures on it.
