At the time the user wants to pause the view, I copy the current data out of the main model into the second model, swap out the paused view's model out to the second model, and then swap it back to the main model when the user wants to go back live.

The only other idea I had was that I could try to change the second view from a pure QTableView to one that inherits from QTableView and then have my own slot that disconnects/connects the signals between the model and that view based on the when the user wants to pause/resume.

This sounds much harder, hackish and difficult to test than simply 
having a "snapshotting" model like you proposed earlier.
