Unusual NAT question

I'm using a 2911 as our Public Internet Edge Router. I have 2 public subnet blocks from Sprint, we are in the process of migrating.

What i need to do is NAT any source address from the Internet from an address on one of our public blocks to the other.

Example:

Source Address 11.10.10.10 ==> Destination 64.165.123.10 (nat this to 64.165.54.10) inbound.

So if anyone from the internet tries to hit 64.165.123.10 we want to nat that to 64.165.54.10 both of which sit on our public space.

You can't double NAT on a router if you are planning to NAT from 64.165.123.10 --> 64.165.54.10 --> private IP of the host.

However if you assign one of the public ip directly to the actual host, then this will work as you are just NATing it once.
