I think if you had a centre steer rack mounted on the frame, dropped near the level of original cross link the bump steer would be minimal. You could also offset it by mounting the centre of the rack below the level of the outer tie rod end .
you are right that toe would change with suspension travel, so this would not work for a truck with a lot of normal travel - like a flexible 4x4, but for a lowered straight axle AD driven on street with maybe 2-3 inches of travel it might be fine.
if you want to keep straight axle and have power steering yet another option is column mounted electric PS. from a prius perhaps. superfastmat on youtube put one in his telsa powerd jag saloon. Maybe this is viable if your current steering gear is all in good shape to keep using
the most well documented way to get PS under and AD is probably a MII crossmember kit
