I fully agree that the current C&P system is a steaming pile of dingo's kidneys that needs a full overhaul. However, the punishment section is going to be laughably irrelevant if people can just taskkill to avoid said punishment.
Newbie killers and trash-tier CG gankers will continue doing what they're currently doing regardless of whatever system is implemented until combat logging is punished.
Perhaps, but I don't think combat logging itself should be addressed until the crime and punishment update. In fact, I think it should be dealt with at the exact same time. The issue with addressing it right now, prior to the update, is that I have no doubt that there will be many players, some from your group and some not, that feel a need to go full texas chainsaw massacre prior to that update just so they can get some consequence free anti social behaviour in before it's no longer anywhere near as easy to do so. I don't like combat logging, but I still can sympathize with those that do as most of the time, the combat loggers are not PVPers but players that don't want to lose some 20 million in insurance money + another 5 to 10 million on cargo by being forced to engage in a battle they cannot possibly win, right? A powerful ship decked out for PVP can fairly easily mulch on non-PVP equipped ships.
Now, if there's an actual permanent consequence to doing so, then so be it. Risk/Reward. You want to be a murderer? Then be a murderer. As long as you accept the risks involved, just like people in the real world accept the risks for being criminal. But until that time, combat logging is a non-issue as far as I'm personally concerned as fixing just that only enhances one of the core problems of this game, which is to say all the players being driven out of Open.
