Uh, No. Derivative works must be transformative in order to qualify for their own copyright. But simply being transformative doesn't give the owner of the new work rights to do anything with it.
Ex: I write and produce a new SW film, and attempt to sell it without a license from Disney. I'm going to get sued into oblivion, because their copyright still applies, in terms of setting up the setting and characters.
Fair use can apply with derivative works (ex: I make a parody version of Star Wars, such as "Troops"), in which case you may succeed in being able to do stuff with your new SW parody, but you're likely to have to pay a bunch of lawyers a lot of money first if they don't like it. But being derivative doesn't guarantee it's Fair Use.
