If Hitler does invade Spain he likely succeeds, at a cost.
Losses and garrisons take down 20-30 divisions at minimum, more if he seriously wants to resist an Allied landing. Meanwhile there goes all of Spain's colonies and islands, likely Portugal's too, over to the British and Americans and since Operation Torch is already going well all he's really done is open up yet another bleeding front for the Luftwaffe. I might also wonder if this, on top of occupying Vichy France, might wind up weakening Germany at some key point like Tunisia or the Eastern Front.
Likely the Spanish Legion(actually a full corps) has to be disarmed as well.
