The 00:00:5e:xxx MAC used by CARP (and VRRP) is multicast. I don't think you can change a multicast lladdr to a unicast one. Wouldn't it make more sense to have multiple (non-carp) addresses on the peering lan, ask your peers to setup a session with both routers, and just use carp to cater for any of your own boxes that need a static route?
