My idea is to write a stand alone SNMP subagent that uses the AgentX interface 
of the master agent.

Perhaps yes. But perhaps it is also possible to implement the whole logic into 
the agent that just requests the performance data from FreeRADIUS.

No new protocol. Just use FR's existing hooks to gather performance data.

The master agent (net-snmp) speaks SNMP and the subagent has the 
instrumentation to get the data from FR. net-snmp offers a nice frame to 
implement subagents.
