I'm not sure if this will answer your question - I may have the wrong end of the stick, so apologies if that's the case.
What you are describing sounds to me like you are wanting your BigIP to become a Reverse proxy - something which I guess by it hasn;t been designed to do.
My organisation wanted to do the same thing - the official response I got back from the SE at F5 was that there is an F5 Reverse Proxy to do this in another of their product suite. I'm sure this is fab, but like you I wanted to try and get this going with BigIP.
BigIP will pass the HTTP URI to the back end server, defined via irule or pool. If the back end server does not bind to a particular host name, or issue full redirects rather than relative redirects you should have no problem.
We have setup a pseudo reverse proxy here - having a single VS - that has a number of irules which depending on the URI will deliver the request to either a WebSphere server, Domino server, or Peoplesoft server. Each of those back end servers have different host names, but to the user, the host name in the URL is always the same. Again, none of our back end servers bind to a particular host name. This works absolutely brilliantly.
Hope this helps - sorry if I have got the wrong end of the stick
Good luck
