Not sure I understand this. There are lots of hands less than opening bid on which partner would bid opposite an overcall - so there is no reason to lower the requirements for an overcall just because partner has passed.
My thoughts
I even think that partner will stretch more to bid after having passed initially and we overcalled.
...or also if we pass and he can balance.
So I'm curious why we should lower our requirements when partner is a passed hand.
