I haven't followed the entire discussion, but I still don't see a
alternative to touching the qdisc layer - multiple hardware queues
need multiple queue states if you want to avoid a busy hardware
queue stopping the qdisc entirely and thereby preventing the qdisc
to continue feeding packets to other active HW queues. And to make
use of the multiple queue states you need multiple queues.
I would love to see your alternative patches.
