Quick question about Copyright of Game Assets

Hello There,

I have a quick question about the copyright policy of EA (and to an extent Lucasarts). I am currently working on a Star Wars related project and was wondering about reuse of Battlefront 2 assets such as models, textures.

Since the law on copyright and fair use is not "black and white" clear, I would like to know if there is a (strong) case if you reuse and edit some models and textures (in a mostly non-transformative way) and (re-)use them to create modifications for other games which will be non commercially redistributed among a small community of people with most likely no market impact whatsoever.

Thanks in advance.
