It does not work at all. the firework will probably has died off by the time 
the swing lens swing to the end of the rotation. The very best scenario is 
that the fireworks will be truncated. Or at different phase througout the 
exposure.  The key is even the the sum of the exposure on the swing lens 
panoramic camera could equal the sum of exposure needed for a fireworks is 
the same it still won't work for the fact that the fireworks happen almost 
instantenous. while the swing lens camera take a finite time to expose the 
whole scene. and at different time too. 

 General exposure guidelines is for asa/iso 100 is f8 and Bulb. try to get 
several  burst of firework in the same exposure. it looks better than only 
one burst.

 You can use your imagination To try to imagine what the burstwould looks 
like in the film. After 3 or four burst  close the shutter and start new one. 
You can use the hat or similar shade to shield the lens during off time (when 
the fire works is not going on. ) to prevent overexposure of back ground. 
scene.

Hope this help.
