Oh goodness, I love Josephine Baker ---positively ADORE her. And everybody should!!! lol. So yea, work whatever ya want into your routine. Think of it like any other form of art: whatever rules it has to define it are there to be bent or broken. Done properly (well-rehearsed, well-structured, confidently performed), anything can be entertaining and thrown into a particular kind of routine like burlesque. It'll be different, but sometimes people enjoy a switch-up of what they're used to.

Be courageous, go with it, and let us know how it goes!!!!!!
