The flipped arm idea only works for 6" plus lifts, but if articulation is what you want, a 4 link front is easy to do, and will make double the current front articulation, but spring and shock lengths become an issue, and when facing a steep down hill the vehicle can "trip over itself" by the control arm becoming the over pivot point, with the wheel jammed and the car rotating over it, ending up in your wagon doing a dead ant impersonation.
A friend has an 80 with 4 link, with the top arms going back beside the bellhousing inside the chassis rails each side, and it gets 48" between bump stop and diff housing, but thats alot of momentum if nose down, and the suspension is compressing to arrest before your winching back on your wheels.
