I love Erika Hernandez but frankly the backstory would be boring unless you crammed in something we never saw on the show, like make Section 31 intensely involved in some element of the NX-02 backstory. Otherwise it's just a bunch of astronauts training and forming relationships they have to leave behind when their mission starts.
I should add that well done it would be quite poignant knowing what becomes of them in Destiny.
To be honest, I found myself skimming or even skipping the TNG parts and re-reading the Columbia parts of the Destiny
I would love to read a novel about how she became CO of the second starship.
