Let's say I have a site with products that have tags, if each resource is available at

GET '/products/tagged/:tag_list/:product_permalink'

Could that be better for SEO than just one permalink?

For example a product tagged "tea" and "coffee" would be available at

GET '/products/tagged/tea/:product_permalink'
GET '/products/tagged/coffee/:product_permalink'
GET '/products/tagged/tea/coffee/:product_permalink'
GET '/products/tagged/coffee/tea/:product_permalink'

I would imagine that google would appreciate this because it gives multiple URIs with different levels of detail about the product, but I cant really be certain. Anyone have any direct knowledge on the topic?

--EDIT-- As John Conde points, this is a horrible idea. What about having the links on my site link to a route such as GET '/products/tagged/:full_tag_list/:product_permalink', and then any time a user changes tags just have a HTTP moved permanently status to the new URL. Therefore duplicate URLs would be highly unlikely and mitigated by the proper response. Would this be better?
