No, it won't. You will never be able to map all the contents of every
VC, by hand, to CBOR without an automated mapping mechanism. The
approach you're suggesting works when you have a small, closed world
model, but fails to scale when you have an open world model.

A mechanism that does this mapping automatically, from VCs to CBOR,
does exist in CBOR-LD:

That's clearly not an option for those that want to avoid using any
Linked Data technologies. I suggest you find a way to do auto-mapping
to CBOR and not hand-pick values in the VC Data Model to convert to
CBOR tags/numbers (artisnal CBOR)... you will fail to achieve CBOR's
benefits when coupling a strategy for closed world models with a
decentralized, open world ecosystem.
