Well, I don't think a pro-soviet regime could survivie too much in Spain in this period. If France and the UK have the will, there is enough internal opposition (basically everybody who isn't the PCE/PSUC or from Negrin ad Largo Caballero's faction in the PSOE) to topple down any communist dominated government, and Moscow is too far to do anyuthing about it, in case they care.
And regarding the WWII. How would the lack of tactical learning by the germans (like air combat formations) affect the Battle of France. Could a less developed doctrine in the german side grant breathing room to the frenchs or those lessons taken from Spain are negligible in the whole picture of the battle?
