formality - "Should" as formal IF


Can a phrase starting with "if" always be replaced with a phrase with a phrase starting with SHOULD? It doesn't seem like we can make a direct substitution. For example, we say



If he askED you to move to Italy, would you do it?



But



Should he ask you to move to Italy, would you do it?



Why is this, and what is the rule for the substitution?
