Not a chance. Blurred Lines lost a copyright case for seeming like it could have been a Marvin Gaye song. You won't be able to use Chad Britt unless it is a satire of Brad Pitt that every judge thinks is funny.
Doesn't mean you're wrong about likeness cases, but the Blurred Lines/Gaye ruling is far from canon at this point.
Had they been even slightly reasonable, it never would have gone that far.
The first would get laughed out of court. The latter would be an obvious ripoff to anyone (perhaps excepting some soverign-citizen-level pedants).
