Yes you can if you apply the needed patches to the kernel and iptables so you can use the imq device. It's a virtual device and you can use the normal cbq/htb/tbf qdiscs on it. You can redirect packets to it with iptables and you can do it from any interface you want and also from IN + OUT. So you can create 1 imq device, redirect all packets that leaves hdlc0-2 and shape on that imq device.
