Cisco Routers, overlapping network via IPSEC

[mrhyd3]

Customer A Network: 172.16.1.35/32

Customer B Network Hosts to reach: 10.1.80.50 & 10.1.40.50

Customer B requires us to double-nat as a single IP i.e. 192.168.19.10 to reach the 10. hosts. Somewhere in between the routing, another 172.16.1.0 network is being used thus Customer B is requiring us to use 192.168.19.10.

Question is, I believe I'm close on the config:

ip nat inside source static 172.16.1.35 192.168.19.10 route-map xx-map
ip nat outside source static 172.16.1.35 10.1.80.50 route-map xx-map
!
route-map xx-map permit 10
match ip address alt-acl

ip access-list extended alt-acl
permit ip 192.168.19.10 10.1.80.50
permit ip 192.168.19.10 10.1.40.50

Need some guidance here, because it's not working. I'm thinking it's not possible to do it this way, it has to be network for network...

A little more info here.

Customer B has a network in the path of the destination that's a 172.16.1.x.

Customer B wants me to static map our internal IP of 172.16.1.20 to 192.168.20.20. Our destination however are two hosts on separate networks (10.2.2.10 & 10.4.2.10)
