RFU

The quick answer is NO. 

At least I'm reasonably certain, but you can always call ETC tech support for a firm No.

One obvious reason is the RFU gets it's power from the console, and is sensitive to cable length, as well as the RFU itself being sensitive to not getting plugged in when the power switch is On (can blow the RFU display).  Thus I'd assume the console cannot support more then one RFU at the same time.  Note that you can have daisy chained RFU ports on the RFU line, just use one at a time.
