Your basically looking at a double triabulated 4 link, done very often in off-roading. The only problem I see is with the stock trailing arms you have no pivot point at the axle end. It would need a bushing or heim type attachment, something that would allow the trailing arm to pivot at the axle to prevent binding as the suspension cycles up and down. You'd be better off replaceing the trailing arms with links also then it would work fine. You can do single triangulated or double trianulated either way. For a lowered 2WD truck a single triangulation is all that is needed. In off-roading where susupension travel is measured in double digits, single triangulatiion can cause some rear steering when one side is full droop and the other is at full compression. Double triangulation basically eliminates rear steer all together in these full articulation moments, but you'll never see that condition in a lowered truck.

Angle for the triangulated links needs to be about 40 degrees or greater measuring angle between the two links (so each link would angle in about 20 degrees from perpendicular to the axle)
