It's a question of "artistic" choice. The decision is between you can do it and should you do it. Is it something that just sounds cool, or does it really add to the scene and the film as a whole? What's nice about post, especially in the digital age, is that as long as you don't work destructively you can always go back to the original. Try it, then listen to it on Tuesday after the novelty has worn off. You can even put the original on one track and the processed audio on another track and A/B them - or even do a blend of the two.
It's times like these that a second set of objective ears you can trust is a tremendous help.
