When I'm running dance floor game I don't use "openers." Dancing is my opener, if I'm forced to say something it's an invitation for a dance compeition with my "friends" over there (Backwards Merge) or to say, "Check out those guys! We can totally show them up!" or something to that effect. Just something to get me into her person space, I dance for a second, step out of it to preserve her comfort levels then reenter.
As for your opener, I like the transition but not your first bit. If you call a woman bored she will be bored, she will be boring, and then she'll blame you for being boring and making her bored. Better off to just come in high energy and go with the old standby, "Hey! I've got to get back to my friends in a second but give me your opinion on something. Who lies more..." If that's a little wordy for you (It may be if the club is loud) cut it down to "HEY! Who lies more men or women?" let her answer, roll off while pushing her away and then reenter with your transition.
Remember you are a high value, fun, and social guy. You don't need a reason to talk to them and you don't want anything from them. Portray that with your body language, what you say is only minimally important.
Don't forget, "Hi!" is a perfectly good opener. The sooner you believe that the better off you'll be
