Proxy CHAP into EAP session

I'm looking for a way on how to proxy / recreate a session into an EAP session. STEPS 1 normal RADIUS session with CHAP password Received by RADIUS server1 2 RADIUS server1 converts/proxies it into a second RADIUS request but as an EAP session towards a RADIUS server2 which handles the full request. Any hints on how to do this? Can it even be done?
