Well, at least your theory explains why his son was born in a stable. Hard to picture an architect being put in that position. Likewise, how could an architect made a living in a podunk village like Nazareth? This new theory sounds like armchair reasoning whose conclusions raise as many questions as they answer.
Nazareth was an oasis on the egypt - babylon trade route.
Not a podunk village.
The word in Luke 2:7 is guestroom. not inn. So the stable of Joseph’s father’s house was where Mary had her labour, because the guestroom was full with the census.
Common knowledge for some.
