Yes you can change springs, but going to an Ohlins chock is not just about spring rate. You will get a fine work of art for suspension. You need to suspend the bike so that rear suspension is unloaded, and pull the thing out. Service manual has detailed steps and torque values for putting it back together.
You can also replace springs in the front fork if you feel that stock are too stiff / soft for your weight.
Why are you looking to change them out anyway?
