In a word, no. You will have to add sound effects, a legitimate process in film and video to make the fireworks sound "right." You may be able to find appropriate sounds on the net for free if you do a search.
You could also try to bump up audio levels and do some manipulation of the sound with your editing software?many non-linear editing programs allow you to equalize specific sounds. A standalone program called "Cool Edit" (now called Adobe Audition) or something similar can also do the trick then just import the audio into your timeline.
