If my understanding is correct of what you are trying to do is:
for a destination IP you are going to figure the source and destination
MAC address. Most of that info is available at the route + hh cache. 
There can be only one destination mac per device and so you only need to
watch the device changes for that. The dst MAC per IP and any changes
you can glean from the route cache created.
But this is based on my understanding of what you are trying to do and
so far i cant say i am 100% clear.
