We have had pictures of pipes through troughs and boxes before.
It would never occur to me to do this.
First of all because it seems extremely unconventional, but it also seems to be a violation of the listing/labeling of the box.
After all, what is the purpose of a junction, or pull box?
Also, how would you determine box fill in deciding if the box is large enough to accomodate the pipe, in addition to the wires?
I know of no volume allowance associated with various pipe sizes.
