The Genmar peg lowering brackets will move the pegs down and forward slightly, but they will also move the pegs out away from the frame. You might also consider a first generation seat, which is flatter front to back, and would allow you to slide back when your knees needed stretching. One more option is to mount highway pegs, to give you the ability to stretch your legs out occasionally. Disclaimer: I don't have any of these options, so I can't say how well they work.
