Low Brass Parade Dance Break Moves?

-I'm in marching band, and during parades we have a dance break (4-6 measures or so). Most sections have a really cool dance, but since we're a new school and only now have a large enough low brass to sound good, low brass has a crappy visual for this. We need to continue marching, and hold our instruments (marching baritone or trombone) but we need it to be flashy. As of now, we just thrust our instruments into the air, which worked as an adrenaline rush originally, but now it's just boring. I need ideas for new moves/visuals for the break. I've already been denied any spinning or loss of step (unless it looks REALLY cool) and I don't wanna lose my spot in line (the mellos switch spots and I almost knocked my girlfriend out with my horn the first few times) so avoid those. Any good ideas would be appreciated. Thanks guys!
