Default XJ: Exo cage idea

This is a quick drawing I did of an exo cage idea. I have never made my own cage before. The numbers on the pic will be explained.



In the first pic I forgot a few parts to the hood cage but oh well. Now onto the explanation.
1. This is the hood cage, I got the idea from the Hummer Atlas II guard and the XJ in 4x4 Evo. It hinges at the two pillar mounts on the bumper.
2. On the roof, I was thinking of building an integrated light bar out of 1" DOM. Not sure if I will mount lights up there or not, but that's why that's there. I would integrate lights into the hood cage but don't want to block the grill more than it already would be, and the lights may or may not come in contact with a recessed winch if I wanted to recess a winch into that bumper. I could also integrate a roof rack on the roof if I wanted to.
3. The pillar rails will be tied into rock sliders.
4. The rear pillar rail and back of the fender flare rail will be tied into the back of the frame.
This is all just an idea, I may or may not want to do this. It could be great, it could be a gigantic waste of time and money, I don't know.

Now you are screwed.

It will be patented and 8 Ball gussets will be added.

Looks like a jungle gym.

Why not make the structure inside where it can be most effective and then put scrub rails on the outside that are mounted to the inside cage? Since it's a unibody vehicle you really need to stiffen it all upanyway, no reason not to tie everything together instead of having 2 seperate structures tied together at the bottom.

If you're that concerned about protecting the body, why not just start with a TJ? That way you can replace the damaged parts easily and you dont have to double the mass to save a dent or two?

The reason why I don't want to put it on the inside is because I don't really feel like screwing with the interior to fit it in there. I haven't really taken a look at the aftermarket cages though, maybe they have something that I won't hit my head on and I can still use the back seat.
Plus, that won't really protect the body. Keep in mind that most of my chances of rolling will be at like 10 mph tops.
The main problems I see with this exo cage might be the fact that I'll get hung up on the cage if I do anything tight. I hear exo cages are weaker than interior cages anyway, but like I said, I'm not going to Jeepspeed this.
I might just plate the whole thing instead, I already plan on plating the unibody frame front to back.
Here are the ideas I used:


Roof design:

I've thought about doing a exo because I'm so big and won't fit in the jeep with a cage inside . I almost don't fit now.

If I were to tie the scrub rails into an interior cage, how much more material would I need? Hybrid cages from what I hear might be the way to go but I kinda feel that an interior cage would be pointless on its own to me unless I roll down a cliff or something.

I'd bet you'd use 2/3 the material that the pictures you posted up would use.

I could lighten up the roof section a bit to save on weight and less of a jungle-gym appearance I guess, and the hood cage could be optional even though I want it for zombiestomping.

At first I thought it would be more, but then I realized I wouldn't be screwing around with the roof at all because it would already caged in the interior. I think the roof would take up the most amount of material.
