I don't think there's a way around using the extra IP addresses if you
want FHRP. Otherwise customers would typically get two /30 networks and
two BGP sessions, providing bette redundancy.

You could use private VLANs (or protected ports of the access layer is
not too large) and still have customers layer 2 separated within that
same VLAN.
