I've captured packets going to a WAN router. I want to play them back at ideally a user specifed rate to a new router model so I an monitor the router's performance using our data in our configuration.
I realize I'll have to configure the MAC address of the new router's interface to match the MAC in the captured packets.

Yes, you indeed need to change the mac-address of the traffic. You would also need to split the traffic into incoming and outgoing traffic, as you would want both to be injected to a different interface (internal and external interface). The the router must not do anything else than routing. Even NAT will break this kind of reproduction...
A tool that you can use to replace the mac-addresses is bittwist

You can play back using TCP Replay. This application exactly replay the captured traffic.
