Another variant:
Taskbar & System Tray > TaskBand > Basic > TaskBand > BackgroundBottom > CONTENTMARGINS 600,3,10,7
Taskbar & System Tray > TaskBar > Aero > Taskbar Show Desktop > Button > Width 700, Height 0
Taskbar & System Tray > TaskBar > Aero > Taskbar Show Desktop > Separator > CONTENTMARGINS 0,0,0,0
Only problem is that you now have a HUGE Show Desktop Button that you will see whenever you hover over it
