I would recommend using AgentX (AgentX++ master + net-snmp subagent).
With that, you can seamless migrate MIB modules into your
smart-snmpd.

The ProxyForwarder (as defined by the RFC3413) cannot
be used because it forwards all requests to another agent
based on a community or context engine ID.

You cannot forward by a subtree OID.

Although AGENT++ provides also forwarding by OID (subtree)
I would not recommend it, AgentX provides a better
integration regarding performance and flexibility.
