I do not quite understand how separate tx queues could help here, because we not only have to transmit off-channel but also receive data. For me simple solution would be adding new functions on top of ieee80211_tx_skb, which will just queue skb's if we are not on operating channel at present, and send them lately when we come back. Or perhaps you are talking about separate tx and rx queues, that could eventually work, but driver still should know how long to stay off-channel to receive all needed frames.
