You can replenish ranks for primal fights now, actually. Ever since 2.1 I believe.

To JemC: You can kick the person that DC'd from the group if they have been gone for too long by right clicking on their name in the Party List in the social menu and choosing to Vote Kick. There should be no issue in getting at least 1 person to agree if your 4th member has been gone a while. After they are removed from the group you should get a pop up asking if you want to replenish ranks. If it doesn't show up or you accidentally close it, open the duty finder menu and there should be a "Replenish Ranks" button.

The only time you can't add members in the middle of a duty is if you queued up as a full party together.
