Not sure if I agree with you on this one, but first my answer-yes I have often increased caster to get more feel. Limited by FFB clipping. The impact on Camber is that as mentioned above, increases in caster increase camber when the wheel is turned like the chopper example. So in my book that allows a LOWER camber when pointing straight ahead. This allow better braking performance through a larger contact patch, but then when in mid corner with some steering lock you get the higher camber. If you have "high camber" you get even higher camber when turning. It is my also opinion that like on the bikes that greater camber also "slows down" the initial front end reaction. It's a tool I have in my "tool box" when I am very happy with most of the corner but would like a car to be less twitchy on turn-in. Mercedes Benz road cars seem to have a lot.
