It sounds like you're describing a hypothetical situation, correct?  It would be unlikely for both DAG members to fail at the same time, because when one fails, you fix it, or replace it right?

Assuming that they *did* both fail, you would need to replace one of them by installing a new member with the RecoverServer switch (http://technet.microsoft.com/en-us/library/dd638206%28v=exchg.150%29.aspx)

Once you had a standing DAG, you could restore from backup.  (You are still backing up, right?)

Once the fires die down, you'll want to stand up a new DAG member and setup replication again.

Whenever you are designing DAG, you need to focus on three component Database, Server and Site-Resiliency. Any one fails, you are at a risk on losing the data. In this situation, last remedy is to restore from backup. As Enphyniti mentioned above, you need to use recover switch to install the server again.
