intresting question
make two ACLs
lets say the know pub IPs
192.168.1.0/24
and server1 ip 1.1.1.1
and server2 2.2.2.2
and your outside ip address is 10.10.10.10
access-list 101 permit ip 192.168.1.0 0.0.0.255 host 10.10.10.10
access-list 102 deny ip 192.168.1.0 0.0.0.255 host 10.10.10.10
access-list 102 permit ip any host 10.10.10.10
route-map server1 permit 10
match ip address 101
set ip next-hop 1.1.1.1
route-map server2 permit 10
match ip address 102
set ip next-hop 2.2.2.2
ip nat inside source static 1.1.1.1 10.10.10.10 route-map server1
ip nat inside source static 2.2.2.2 10.10.10.10 route-map server2
and apply ip nat inside o the inside interface
and ip nat ouside on the outisde interface
after apply these config reload the router then test
if it didnt work try to remove the next-hop statment from both route maps then also reload and try
good luck
