As per my understanding, that is possible. You can have multiple Public IP NAT to a Single Private IP. This works fine for incoming traffic. But when traffic going out it will always hit the first NAT rule and use that one. 

 

nat (inside,outside) source static WEB-SERVER WEB-SERVER_PUBLIC_01

nat (inside,outside) source static WEB-SERVER WEB-SERVER_PUBLIC_02

nat (inside,outside) source static WEB-SERVER WEB-SERVER_PUBLIC_03

 

You got my point. You can also add Services to use particular IP for a particular service. 

 

nat (inside,outside) source static WEB-SERVER WEB-SERVER_PUBLIC service TCP80 TCP8080

 

 

 

I hope this answers your question.
