I think if you set it up right - lead into it, make sure she knows it's coming, and actually do the dance well (maybe slightly less aggressive and dramatic in movement) - you could get your desired reaction! At the very least, it'll be adorable, and that's not a bad thing for a husband to be. No matter what, a clear effort towards sex with someone you're married to and in a different way than normal? Going to lead to sex, and probably with more passion/enthusiasm because it's something different. She'll appreciate the effort and your results will be good, even if they aren't exactly what you expected.
