The fact that you only respond like this anonymously should answer your original question/not-a-question.
from a more practical perspective: No, because you're replacing a well-understood metaphor with something that is unknown, juvenile and stupid, removing the value we get from shared language constructs.
By exaggerating the example and moving out of shared constructs I was trying to get wegfaw... to see how it is to be "annoyingly sensitive". That even though "hit by a bus" is "well-understood", it could still invoke very graphic memories if for example someone actually has lost someone in a bus accident. Sometimes words are not just words.
But i could imagine someone who states that it's his "right" to be as irreverent as he likes to whomever he wants to is not open to the concept of other people's perspective.
And just to be clear, I wasn't saying that you should use my example instead. :D
