        I'd probably stack ipAlias VIPs on the CARP VIP, make an alias of the ipAlias VIPs in the pool then use that alias as an outbound NAT translation. When you set a NAT translation to something that can contain multiple addresses (alias, other subnet) you get the pool options in the gui.

          It depends on how the IP addresses are routed to you.

          If you have a block of routed addresses and the upstream ISP is routing them to your WAN CARP VIP – nothing special, just add the subnet in outbound NAT

          If you have a set of VIPs to use instead, then make an alias of them (a host type alias) and then select that alias for use in outbound NAT.
