Custompress Duplicate Taxonomies

I’m developing an e-commerce Store

I am trying to develop an ecommerce store with the normal categorical tree: like electronics->Monitors, cameras etc.

But also want this hierarchy to be sortable by a brand taxonomy.

So you could click yellow, and it still had the same hierarchy but only the yellow brands.

I can’t figure out the best way to implement this.

Another thing, I will be using a role manager plugin to allow different store managers access to different brands.

Any help would be greatly appreciated.
