I don't think there's considerable gain in splitting this into two steps.
Basically, what you'll be doing is distort the flip operation:
fx(x) = xmax - x
by replacing the straight-line function fx(x) by a curved one.
E.g. one like the usual "gamma compensation":
fx(x) = (1 - x/xmax)^gamma * xmax
The further away gamma is from 1.0, the stronger the effect.
