Force a next hop for a VS?

I would like a VS to load balance between nodes, say 10.0.10.11 and 10.0.10.12. There is a route for 10.0.0.0/8 in the TMM already, pointing to a Firewall outside interface, but i want the F5 to direct traffic for 10.11 and 10.12 to a firewall INSIDE interface if it arrive on a certain interface.

Is there a way to force a next hop for a VS, overriding route table entries? If so a VS on that interface would be a solution. Or is there another way? I would like to avoid Route Domains if possible.
