The scaling of at least Peace of Mind appears to be calculated using at least your character level and values stored in \Data\Public\Shared\Stats\Generated\Data\Potions.txt. By altering the values in Potions.txt you can change the scaling/values per level.
However, there appears to be one very important thing to take note of. From my testing, the values stored in Potions.txt are peak values when your character is around level 13 (~950,000XP) and they will continue to rise as your character level increases. Conversely, they will decrease proportionally as your character level decreases below 13. So, this can make it slightly more challenging when you want to alter the scaling.
I prefer to play normally with Vitality*Scaling set to 1 so I had to find a way to adjust some skills and potions for balancing reasons (vitality scaling appears to have no effect or little effect on some buffs and potions). While I may not be doing it correctly, it has proven sufficient for my needs (keeping achievements enabled).
I hope this information somehow helps you accomplish your goals.
