Yes you can. However, iptables will not work on a bridge. So you have to use
the u32 filter (there is a patch to get iptables working on a bridge).
If you shape on a bridge, you can shape on both interfaces, so you don't need
the ingress capabilities of the wondershaper. However, you introduce an
extra NIC in the data path, so you also introduce extra (small) delays. One
of the benefits of ingress shaping, is that it does not introduce extra
delays, but it's not so powerfull as egress shaping.
Or you can replace the switch with a linux box with some quad-NIC's.
