AFAIK you can only change the settings for display to get to that behavior, kind of... See for yourself if this would be sufficient:

Go to settings -> display, -> disable "lock screen automatically" and set the "backlight time out" to something convenient. If the screen simply times out, as opposed to manually switching it off to lock the device, your screen should turn on with a simple double-tap and take you directly to the desktops. Does not work when you do it manually.
