Can I conditionally proxy?

I have used FreeRADIUS before as a RADIUS server but I now wish to use it as a conditional proxy.

We have two RADIUS servers that implement 2 factor authentications.   We wish to migrate from the old system to the new system a few users at a time.

I would like to setup FreeRADIUS to do something like this:
if (the user is in a particular AD group) {// I can do an LDAP lookup, if necessary
proxy to the new 2fa system
else {
proxy to the old 2fa system

Can anyone help with examples of some sort of conditional proxying?
