Portugal-Spain Union

Is there any plausible POD in the 20th Century for Spain and Portugal to become 1 country? First thought was the overthrow of the Portuguese monarchy and the second during the Spanish Civil War.
 
I bit doubt Spanish-Portuguese Union. These are quiet different countries and had pretty different 20th century. Perhaps some kind of military or economic alliance is possible

Only way that there could be unified nation is that Portugal becomes socialist state instear Salazarian state. Then Second Spanish Republic survives and they unify as Iberian Federation. But I doubt even that.

Not that I can see during the 20th century. You would need a really early POD to make it work. Portugal has been an independent country for nearly 900 years.
