I understand the desire for something elegant, believe me! This might indeed be doable, but I'm afraid I don't have the math to work out the exact relationship. However, one thing I want to point out - this modifier, whatever it is, shouldn't be a bigger limitation than Variable Costs Fatigue. The way you have it set up, someone with simple Variable Costs Fatigue will always be paying more FP per level than someone with this pricing scheme, except at the very highest level, when they pay the same amount. That means this is definitely going to be less of a limitation than Variable Costs Fatigue.
