Dear blrmdncr2000,
How about using Shadow Position? Whatever dance you choose you will look like you are "flying in formation"--especially if you have some progressive moves.
I myself am preparing for showcase. It's a Foxtrot where my female partner and I start off with Forward and Backward Twinkles in Shadow. I know that my showcase features an American Smooth dance, but I believe that the effect of being in Shadow would be the same.
Going into and out of Shadow can also be a very striking part of a showcase's choreography.
Good luck and have lots of fun!
