It sounds like you've already "closed the loop" so to speak, but regardless I think your options are the same:
1) Recruit those two additional accounts from whatever other account(s) you want
2) Start over (so that RaF time is in sync)
3) If accounts are < 30 days old, then ask Blizzard if they can help you recreate your recruitment chain
Unless I'm misunderstanding, what is stopping you from just continuing the chain? Like this:
Code:A > B > C > D > E | A
