No. I don't think this will ever fly by the crypto folks in this form due to the CRYPTO_ALGO_ASYNC fallback parts which are necessary to get it to work with mac80211. It would be a great if mac80211 would do to the encryption and decryption asynchronously. As this would work for other ciphers and also allows crypto offload to dedicated crypto hardware.
