To me it looks like you are running a wishbone three link, but i'm not sure what the bar that runs from left to right on the lower bars is for. Maybe i'm missing something. The concept of the drawing should work fine. The closer you make the center pivot to the bag the more lift that you get at the other end. You may have to find a different way to connect the bag to the pivot bar as the bag might try and bow out. It looks better on paper then the setup thats on the first pic. It looks as though the upper bag bracket will bend because the gussets don't come out far enough and the lower bag mount is going to try an twist the hell out of that lower bar.
