this is possible with incoming packets, but, how do you select the
source of a new one?

This could go wrong in so many ways i would not even try:
i.e. how do you determine if a gateway is up? dont tell me icmp, many
firewall refuse it, and vrrp standard says the backup gateway should not
answer icmp echo.
