You'll need to understand some more of the technical details of bitcoin's operation before you can think clearly about this.  The seminal bitcoin paper (google for "satoshi nakamoto paper") is a good start.  Many of the things you propose would be hard to implement in a bitcoin-style framework.

As for your question about how to create one, someone will have to implement it in software, someone will have to market it, someone will have to develop user-friendly tools for manipulating and tracking it.  You've got your work cut out for you.
