traps sent from an SMUX subagent processed by snmptrapd?

hi,
 
we are currently running ucd-snmp v4.2 and are looking to upgrade to
net-snmp v5.3. The documentation mentions that this net-snmp version
would support existing SMUX subagents.  we are evaluating whether it is
value added to re-write the existing SMUX subagents as AgentX subagents
or Proxy subagents.  we are planning on utilizing the snmptrapd feature
and were wondering if we left the SMUX subagents as is, is there is way
to configure snmptrapd to process/receive the traps sent from an
existing SMUX subagent?
