BlueZebra asked the most relevant question, as if you are all in business class, you will all get access to *A lounges (departure or connection only, not on arrival). You are correct that you can only guest 1 person into a *A lounge with your *G status, so that won't help unless your spouse also has status. PP doesn't have access to any *A lounges in BCN, MUC or BRU, so that won't help you. LH suspended lounge pass purchases, you might want to check in the LH forum to see if this is still the case.
