Would make a good novel to explore that history, like a Spock's World kind of novel focusing on the history of the Romulans.
Err, that's what The Romulan Way
was, and it came before Spock's World
. The Vulcan's Soul
trilogy also explores the history of the Sundering, although oddly enough, the first volume contradicts the Diane Duane version with regard to Surak's role in the events leading up to the exodus, while the second adheres to it quite faithfully with regard to the specifics of the interstellar journey.
