3 piece wheel information

[frankendat]

I have never owned three piece wheels and haven't been able to rectify my question from Youtube or Google. (This happens when I am way off the mark, but I still desire the answer) 

Three piece wheels consist of an outer lip and inner barrel and a center piece. When inspecting a three piece wheel, aside from width, I cannot find a notable difference between the outer lip section and the inner barrel section. I am curious if a three piece wheel constructed of two outer lip sections and a center piece would be fine. (if width was not an issue)

Additionally, what is a "reversed" outer lip section?

Outer lips are going to have valve stem holes.

Reversed outer lips traditionally had the center section reversed so the inner wheel half now faces the outside and gives the wheel a lot of offset towards the outside of the car. The video below shows a steel wheel being reversed.

A modified version of the previously posted picture provides opportunity to re-try my question- Thank you

The wheels would be built in either a positive offset or a zero offset configuration. I lean toward zero offset for simplicity, but what is available at bargain prices often dictates build path.

I understand the use of masterfully manipulated photo images might be intimidating, but please try to keep up. The image inserted into this post is the previous "zero setback" image. It presents very much like a three piece wheel. If it a three piece wheel, then the inner barrel (marked with a red line) and the outerlip (marked with a green line) would bolt together. The bolts would pass through and anchor the center section, which is the black piece in the center. 

 

Evidenced in this image and keeping with my limited experience, The "raised" section (before the step-down) of the inner barrel is longer/wider than  the raised section of the outerlip.

Here is an image of my question, it is the zero offset image, but the outerlip was removed, the inner barrel duplicated and flipped, then reattached. The bolt holes will still line up and center section would not change. As both inner barrels would be the same the wheel would remain basically zero offset. I photo shopped two inner barrels, but it could have easily been two outer lips. 

 

Ratsun Brain Trust, I can find no explanation why this would not be fine and dandy, but can find no example of it, or even anyone who has heard of it attempted. I welcome your thoughts.

Some have used inners for outers and vice versa. I have zero offset wheels with the same size barrels on both sides. It would change if the center section is a weird offset.

Zero offset wheels work with two outer lips? Sounds like YES

It sounds like for zero offset wheels all is good, but why can I find no examples of it?
