I don't know if it still works on modern switches, but many years ago I
was able to have Cisco LAN switches configured such that a single L2
MAC address could be statically associated with multiple interfaces
(i.e. router interface).  This made it possible to duplicate all
traffic to destined to one station to appear on two (maybe more?) ports.
You might try this also if you have an unused and available switch.
