Might be important, but it didn't happen. Let's leave aside all the unknown foreign wives that were never recorded.
The minimal record we have, mostly of the women in the royal line of his ancestry, indicates numerous Ammonite, Egyptian, Tyrian and other foreign mothers of the kings.
Christ's human ancestry, like that of every other person on the planet, was not "pure," it was thoroughly mixed.
The Israelites themselves were never a "pure" race, in fact their Law contained specific provisions for marrying foreign women captured in battle. As one example, Joseph married an Egyptian women. Therefore, his two eponymous sons, Ephraim and Manasseh, were half-Egyptian.
Joseph married Asenath her father was Pontipher the Priest of the City of ON which was built by Enoch. The Priest were from the line of Seth. This is the reason Jacob/Israel made both of Joseph and Asenath’s Sons a tribe because of their pure lineage. Joseph adhered strictly to the teachings of Jacob. Your deductions remind me of the universal church spoken of in Revelation.
