No, that does not mitigate the issue. What you're missing is that ARP
cache poisoning does not change host MAC address, but the association
between a MAC address and an IP address in ARP cache.
In addition to pointers that were already given, you can try this one

One other mitigation technic is static ARP cache entries, but it can
become painful to maintain quite fast as network grows.
