1 to 1 natting without internal ips.

I want to create such policy which forwards incoming request through endian to internal network which is connected to green interface.
A sample of policy is attached as picture to this post.
Would it be possible?
For example;

source interface=red
source address= ALLs
source port=ALL
destination interface=Green
Destination Addres= ... (want to assign here a wan ip which will be behind endian)
destination port=80
allow

Will latest version of endian allow us to do so?
Thanks
