Other than all that arguing chaos that's already been thrown up there (not going to touch that with a big stick), it seems like instead of these attacks in the major sectors, a more logical choice would be the major trade chokepoints. The biggest thought I would have is southern Shikoku. It would be way cool to see some QCP block off southern Shikoku and the adjacent systems, possibly basing at the place in Kepler/Galileo (can never remember which is which). That does represent a huge portion of Kusari trade - the other huge chunk going to Rheinland and such.
