If you can stand the climb over the door bars and you put some reinforcement in to tie the angled down legs to, I can see justifying it. You will stiffen the chassis a lot with that and be a lot safer at the same time. A six point is good with subframe connectors to tie the fore and aft together, but the eight point with some 14 gauge to 1/8 inch plate sandwiched top and bottom and tied to the center down legs adds a lot of torsional resistance.
