I don't understand the last two sentences. (I assume the router is the box
connecting your public network to the ISP). But lets put that aside for 
the moment. 

The VIP is a routable IP, so clients on the internet can send packets to
the LVS. The real-servers will also have the VIP on them, so they can send
replies to the client. The RIPs on the real-servers and the network
connecting the director to the real-servers can be anything you like,
including non-routable IPs (ie 192.168.x.x).

Can you explain your problem again saying why this framework won't work
in your case.
