If you want stats or skills that badly, just use that marvelous, and amazing thing that millennia of evolution has given you called a "brain." Then use that brain to conjure up yet another wonderful thing that humans tend to do called your "imagination."
AKA, use your imagination and as you play the game you are gaining stats and skills which you put into your imaginary stats and skill trees.
Because what you're mentioning isn't a "few hours" or "few days" of extra stuff that the dev has to do. You're talking at minimum months extra time, because he would have to add alternate scenarios, more rendering for those scenarios, the coding for adding unnecessary stat and skill trees, etc.
It's not gonna happen, man. It's a great AVN, even if it doesn't hit all your boxes perfectly (for me, it's a little too much girl/girl stuff, but I use that imagination of mine to mentally change the scene to where it's MC/girl). Just buck up and enjoy the ride.
