Using the same IEEE 802 MAC address on multiple router ports will cause 
problems with VLAN learning operation (e.g. same MAC address would be in 
multiple VLANs so the interface will receive traffic on VLANs it doesn't 
belong to), so this is not a good idea (which is why routers or bridges do 
not do this).

This wouldn't cause a problem because DHCP runs in parallel and if a 
different address were assigned it would over-ride.
