SNMP v3 TRAP forwarding/proxy

I have a system where network devices will generate SNMP traps using v3 to ensure  that the data is encrypted across a WAN.

My event collector however will only support SNMPv2. Changing to a different collector is not an option, it collects and analyses event from a number of sources and not just network devices.

I need to find a method of receiving an authenticated and encrypted trap from my network device, and then forwarding this to my collector using SNMP v2 over a local LAN. This conversion would be on a trusted network so the lack of encryption between the converter and the collector is no longer an issue.

Can snmptrapd do this? Is there any other component I need?
How do I configure it?
Is there any other solution?
Any other points I should be worrying about? I know about the IPaddress issue with the forwarded message

A Windows implementation is preferred but Linux is not out the question.

I think I have successfully configured snmptrapd to receive SNMP v3 traps. I can't figure out however how to send them on to my event collector using SNMP v2c TRAPS. I should not need to process the MIBs as the event collector understands SNMP v2 MIBs. The documentation on proxying only appears to talk about proxying SNMP v2c gets to an SNMP v3 device. This is not what I need.
