you would do - not sure about the feel though as people have various interpretations, but for the steering weighting you're pretty much just increasing the unsprung weight, and what this achieves is a greater gyroscopic effect - think about a bicycle, when you go relatively fast the wheel is relatively harder to steer, as the gyroscopic momentum of the wheel keeps in upright and going straight. That's what you'll get with bigger, heavier brakes, leading to an "unwillingness" of the wheels to turn in comparison to the lighter brakes, which in turn leads to more steering weight
