Russ, That is indeed an interesting use case. Does this mean that you are really more interested in using this as a content encryption algorithm rather than a key encryption algorithm? I have doubts for this use case that you are looking to wrap key and are looking to wrap content. This is different than a use case where one wishes to use an HMAC algorithm with a key which is not a multiple of 8 octets.
