As for the general concepts you are thinking of, with the right background to explain why they have turned into an adventurer, they might all work. Some of them are more like NPCs in my mind on first take though.
But to base a concept on CotCT campaign traits might be premature (again not building sheets yet), because if things continue as planned there might be three GMs with games going and only one (mine) is running CotCT.
I admit that I do tend to go for the Everyman theme in most of my characters. Ordinary people forced by circumstance to do extraordinary things.
