If you have the same force per square inch/mm then you would be correct. Your brake pedal input is divided up across the area available, if you increase your bore size then the area available is greater hence a lower force per square whatever, but you will displace more fluid for a given pedal travel hence the pedal feels better by being both shorter & feeling firmer. Larger discs will give a greater mechanical advantage to the calipers that will lessen or negate the effect of a larger bore, of course bigger discs take up more room in the wheel envelope meaning that Tickford rotors allow fitment of 15" rims. Another thing that Tickford do for pedal feel is use a different pedal ratio on some models (not sure which).
Can I go back to my hangover now!!!!!! please!!!!!!
