You've got it backwards. Increasing the fork rake (offset) results in less trail, which in turn speeds up steering and decreases stability. In order to maintain a certain amount of trail, it is necessary to decrease the frame's head tube angle when increasing the fork offset. If you really want to increase stability, then reduce the fork offset while maintaining the same head tube angle, which will increase the trail. The main advantage to increased fork rake is that it provides clearance for wider tires and also allows the fork to flex more for increased comfort on rough surfaces.
