Hey Sean - the use of the Liszt music will really add comedy and theatricality to your piece, so yeah, go for it. Just one query - I'm just not sure why the ballerinas have the ball bearings in their tutus to start with? Maybe you know better than I - maybe they do - but otherwise it does seem very 'forced'. Really, you need to get the ball bearings introduced somehow that feels more likely; your story doesn't have to change at all, because as soon as the balls are involved, everything plays out the same. You might consider simply having a stage-hand knock over a jar of them off-stage - or from the lighting rig above, or similar?
