I have the perfect role for you. There is a TV Series and a Movie called 'The Trip'. It stars Steve Coogan and Rob Brydon playing versions of themselves taking a tour through the Northern England eating at fancy restaurants. What's great is how they talk about the craft of doing voices. There is an awesome scene in the beginning where they do dueling Anthony Hopkins.
Generally, I tend to hate remakes of British films, but this is a good exception because you can bring more of yourself into the role, and you do different voices.
