I don't think this is necessary. As it is now, when you enqueue a packet in a full SFQ queue it drops from the tail of the longest subqueue. If you have substantial competition for the link then your subqueue won't be allowed to grow very long to begin with. The random variation in demand from other flows will have the effect of jittering the maximum length of your subqueue, which is pretty similar to what you experience with RED, isn't it?
