 This won't work, at least not the way you stated it.
Router 4 has to know about Router 1

This works:

 Internet <---> Router 1 <---> Router 4 <---> Target

It is the layout of the network I work on every day.
well ok it is actually

Client <---> Router A <---> Router B <--->Internet <---> Router 1 <--->
Router 4 <---> Target

(my WS)      (firewall)     (Sprint BB)    (routes)      (DSL host)
(Firewall)   (client WAN)
