Are there any exercises that you've created in order to further develop your own personal style?

For example, a baseline creating tool that I've developed is to think of a bassist and than think of a band that would be ridiculous for them to play in. For example, what would a song sound like if Aston Barrett (The Wailers) was forced to play in Joy Division or what if Geddy Lee was the house bassist for Motown. This helps me to "get out of my own head." Do you have any similar exercises?
