I really like this idea. Likewise, if you didn't get the approval bonus/penalty until discussing it at camp with members not in your party. Like your companion approaches you and says something like 'Hey, I heard you handled this situation this way. Wtf man." Then you explain your position which can maybe net less disapproval, more disapproval, or maybe even approval if you pass a persuasion check. It would feel like a far more realistic way of disagreeing with someone while still being able to earn their friendship. (Hey, we've all had friends who we don't agree with all the time, right? But honest, open debate can still foster healthy respect. Unless you murdered an entire orphanage. No real talking your way out of that.)
