I am not an expert, but while you are waiting you could be working on getting all your source documents together such as sources for birth, marriage, death.
This way when they clear the way for the merge you will be all set to go. The same thing sort of happen with my grandfather. Someone else had his profile so the other profile manager gave his profile to me and I became the profile manager.
I would focus on collecting your source documents.
Hope this helps you a little bit.
