The following thread appears to confirm that the WD drives in a "My Book Pro Duo" RAID store the encryption key and RAID metadata in firmware modules 25h and 38h. Transferring these two modules, and module 02, to two clone drives enabled the cloned RAID array to be detected and decrypted by the enclosure.

Here is a 16TB My Book Duo with two HGST/WD helium drives:

ISTM that if one were to intercept the SATA interface with a protocol analyser, one may see the VSCs that the bridge transmits to the drive when these firmware modules are updated. Could this be the secret to cracking this new architecture?
