Hmm. I don't know of any such "app" or module for this, but this can fix your problems:
Install GravityBox (KK) > Reboot > Set a custom key in the navigation bar > Set it's function to open Notifications Panel.
This doesn't let you "swipe down" from the screen, but atleast you can get to the notifications without having to reach out to the top.
