Yup, I did the mod myself. All I did is adjust the spacers that were on the joystick shaft so less stuck out of the top.
I have heard of others completely replacing the joysticks with Happs Joysticks, and the way this thing is designed would make it easy to do so. I definitely found I play a lot better with this thing. Particularly Shoot-em-ups.
I am sure you will get even better than you already are if you start using one.
