    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.

Why would you need to ARP again? You already have the protocol address
to hardware address translation, so why do you need to get it again?
Maybe you have a very, VERY small ARP cache timeout?

This doesn't answer the poser's question though, since I think the poser
wanted to know how to rechoose at the IP level, not at the link level.
