I don't want to intervene the discussion around whether this direction is
correct or not, however I want to say request_key() may not be the right place
to fit Quote (or remote verifiable data blob in general for attestation).

Although both key and Quote are data blob in some way, Quote certainly is not a
key but have much more information. The man page of request_key() seems to
suggest it's just for key:
request_key - request a key from the kernel's key management
facility
So IMHO using request_key() to fit Quote may cause bigger confusion.
