Reverse actors HP MP progression

Here my new weird question:

Is there a way to swap HP and MP progression, with regression?
The same about swapping HP/MP increments with decrements...

Here's an example:

Terra lv1: HP 40 ---> Terra lv 99 HP 9992 average increment: +100 HP

After the change:

Terra lv1: HP 9992 ---> Terra lv 99 HP 40 average increment: -100 HP
