Unfortunately no because the problem is not as simple as taking a fight to an Anarchy system. I am a member of a player group whose BGS faction is a Dictatorship. We recently engaged another player group in a PvP only war. Their faction is a Democracy. So we make PvP wing raids into their systems and they in turn come to ours and we all have a good fight.
But 3rd parties occassionaly get involved, some of which come to troll. They engage us and then turn crimes on to get us wanted in our own system. Without precautions to prevent this type of trolling the new C&P improvements will put PvPers like us completely at the mercy of some random trolls ruining our fun and/or preventing us from chasing them out of our system without costing us 6 days of NPC hassle and the like just for being the good guys and blowing the nuisance trolls up.
Then if you are not willing to be trolled, there is no reason whatsoever that you cant create a Private Group for this Player Group PVP battle. Everyone else has to when doing anything that might get stream snipped. Why cant you use those same systems?
