Since the destination MAC address is only determined by arp table
lookups after the routing decision has been taken, at least when you're
using you Linux box as a router, you can't do much about it in the pre
routing table. I am also not aware of a standard target that let's
you modify the destination mac in the post_routing table.

But if you are using your box as a bridge, you could you ebtables to do
some sort of MAC NAT. => http://ebtables.sourceforge.net/

The question is: what are you trying to achieve?

I guess you need to use ebtables dnat for this yet.
