The Hockey stick and it's motion is more or less a 3rd class lever (the force goes between your shoulder (the fulcrum) and the load (the puck))

Levers rely on two things, the material they are made off and the length of the stick. All of this follows the ration L/l = R/E

L= length of effort arm, l = length of resistance arm. R = resistance weight and E = Force applied. Now then, shortening the stick lowers your effort arm, therefore making the left side of the equation drop. This makes R/E smaller, so either the Force applied must increase or the resistance weight must drop (but the puck is constant so it won't).

Therefore, in all that physics jargon, the following can be extracted. Shortening the stick means you must apply more force to get the same leverage. AKA: the stick feels/works as though it's stiffer even if it isn't.

Note: All this assumes your lower hand position is the same before and after you shorten the stick.

Yay for being an engineer hahaha.
Yay for grade 8 science.

On topic, I don't beleive its possible for you to shorten a stick without makeing it stiffer. Even this oggie grip stuff what it is it? The sticks I've known have become more flexible with use so if you cut then keep useing it for a while then you might get the original flex back or close to.
