Seems reasonable. Internals to the NSC should be kep as such (especially, the second and third bullets of your list). 

Another approach would be to focus only on the visible external behavior, e.g.,: 

- The network exposes its (slice) capabilities
- The customer requests a slice
- The NSC maps the requests to the capabilities while applies provider policies (if any) and then creates the resource partition
- The NSC reports back to the customer as a function of the previous step

Cheers,
Med
