I've rewritten "Takeover" up to page 60, or about 20% of the way. But it was by far the hardest 20%. It should be much easier from now on. Almost all the chapters that don't include Nicole or Hart will be fine as they are. The relationship between Nicole and Hart is what has to be changed, In the original version, they don't know each other. In this version, they are already an estranged couple with a history.

It's a tricky thing to change. First solution is just to throw out anything that doesn't fit. If the passage contains information needed for the plot, then find another way.

Second solution is to write new material that is more in line with the new story.

I'm not sure how hard this is going to be. Anywhere from easy to impossible. Just need to start in and see what happens.
