We once did a thing where we picked an Internet Address that all gateways
would respond to.  When a host did an ARP, several gateways would respond,
and the host would pick one of them (I imagine the last, but it rather
depends on the host).  If the chosen gateway died, then subsequent ARPs
would find a living one.

In ISO (by the way), we have a host to gateway configuration protocol
(called ES-IS) that has a LAN multicast addresses that means "all gateways"
or "all hosts".  When a hosts hears "all gateways", then he gets the
packet, and records the internet level address (Network Entity Title,
in ISOese).
