Using freeradius as proxy for EAP-SIM/EAP-AKA

  Hi   I am wondering if it is possible to proxy EAP-SIM/EAP-AKA authentication using FreeRadius ?   Assuming brand X radius server has support for EAP-SIM/EAP-AKA, but it's located at the final end of the food chain, and in-between the brand X radius server and the Access point, there are 2 (or more) radius servers which are doing proxying ( and some other non-EAP SIM/EAP AKA work ).   Will it work ?
