Add new textures to Old art item, or make a new one?

I've been commissioned to make more of these medieval signs.

http://opengameart.org/content/4-medieval-inn-signs

 

I'm trying to get a sense weather it would be more or less confusing to edit that item and add the new content, or make a new art "item" for the new textures.

 

Opinions welcome...
