Don't try it, especially if there's code and/or liability factors involved.
The smaller sizes can be jammed together, but all throughout the size range the thread pitch and thread forms are incompatable.
NPT to BSP "adaptors" are available to let you properly sanctify "mixed marriages" when needed.

That is the definitive statement on the subject.
