Maybe you can give us the best of both worlds, to a point where the the Breakers are fairly new and have just overthrown the Doomraisers, it doesn't change much except for the fact that everyone will still be working out their relationships and their goals onward (which is desirable, as trying to convey a gang society without any prior talking or posting is difficult), giving us a plot to focus on and the foundation of what the breakers will be to figure out. That way the counter-attack plot can make sense.
