I have just made this exact change to my HH and its much lighter with whoopies than the stock suspension. Before I made this change I altered the way I hang my Tarp so it would not sag as much when I got into it.
I do not use a continuous ridgeline as some here do. I use a cord from each of the tie outs on the ridge of the tarp.
Its not the best way for all but it works for me.
