I like the idea, would be helpful to include (if not already) where the product is sold. Toyota famously added a small metal block in the US to pass IIHS's small overlap crash test but that small block doesn't exist in other Asian countries.

The modern production line is so efficient they can do that level of customisation for every market individually...

That's a cool idea ; feel free to use https://www.haaartland.com/ for this.
