So going to harder bushings means more consistent and improved suspension geometry under loading (bushing keep suspension pivot and mount concentric), increased feedback, as well as increased noise transfer to the chassis.
I would recommend starting slow and with the more common bushing upgrades to see how it suits you. It's not uncommon for people to go to far with this and have to reverse their work as they pass the threshold into irritatingly stiff, loud, vibrating, etc...
