This.... this sounds interesting. I like the idea.
On the topic of the lawful good paly, I think the best I saw was with a group that were planning an ambush of a small goblin camp at low level. Thief and ranger wanted to sneak in and kill some before they were noticed, and the wizard was ok with it. Even the cleric was like "well, they ARE evil monsters so my god will be happy as long as they are dead." Paly was being expected to be against it though, so they tried planning it out of earshot. Player with the paly rolled a perception to hear and won, and you could practically hear the table groan about what they expected. Paly headed over and she basically said "I heard you planning something dishonorable, and I can't approve. If you did it I would be very disappointed, both that you would do something underhanded like that, and that, tactically, it would be more effective to target the shaman and not the watchtower guard first. Now, I am going to go over here and pray to myself and leave you to think about what I said. If you end up in combat by mistake though, just use the signal whistle and I will come running and engage in honorable battle."
They could have easily been annoyingly meta about the way they were willing to let the plan happen, or just stonewall "I am law!" mindset, but I loved how it felt like something a worldly paladin might do, knowing full well the world itself wasn't always fair combat.
