Can I duplicate scene with different artworks.

No you can't because rendoring uses all the assets currently in the scene so you have to swap out the texture maps by hand between rendors ... Also the way Dimension works would suck up enormous amounts of Ram trying to do what you want 

Hello, you can set your design with artboard and change on the fly by choosing the artboard for the decal or the background. 

If we can see a screenshot of your scene i can be more fine in my explications 😉
