The particle engine in DBPro would be a good system to mimic your flares. You can set the particles up however you like, gravity and stuff like that could even be done by simply changing the particle gravity settings. Actually laying the mock performance out would be fairly easy, just make a particle object for each flare and position them where you like - you can then simply adjust the particle emissions and change the colours if you like.
The demo should answer the question for you, just download it and check the particles example supplied then mess around with the values and see what happens.
