Nodir,
Let me try to answer your question. Please correct me if I am wrong.
"set ip next-hop" in the policy routing only work when the next hop ip
address is the address directly connect to the policy-routed router. It can
not be any ip address not directly connected such as loopback int.
In this case, it will not do any good to load balancing.
