comment For a non-convex function f, how to find a function g such that $g\circ f$ is strictly convex?
To add to Pietro comment, if there is a point with three preimages by $f$, say $x_1$, $x_2$, $x_3$, then $g\circ f$ must take the same value at these three points, and thus is constant.

comment Unusual generalization of the law of large numbers
I am not sure I understand your notation. Anyway, I suggest that you apply the LLN to the total variation of your measure (which is a positive measure). $1/n \sum X_i$ is converging to $1/|\mu|(X) \int X d|\mu|$ for a complex valued measure, not to $\int X d\mu$.
