I don't believe that is possible. They usually have three idols at max in a season, and late game only one person can win immunity. Due to the fact that on most seasons the idol can be played up to Day 36, there would be five to six castaways left. This means at most four castaways are immune, and at least one is vulnerable. In this event, the one or two persons will be eliminated.
-But in Cagayan, there was an idol hidden in each camp, and then the god mode idol after the merge, and it could be used up until F5.
