I've no doubt this can be done but I'm not sure how this is legally different from an
encrypted backup for which the passphrase has mysteriously gone missing when
your favorite TLA drops by for a chat. The backup in question may be utterly
irretrievable but given current and pending legislation in various jurisdictions, the
mere presence of physical media with random bits may be enough to land you in
hot water despite your protestations.
