Tom, I've done this with my 746pro and also with a WinRadio Rx. You get all modes plus whatever audio the 2nd Rx has. With the winradio you even get to use the panadapter to help tune the RF and IF.

I picked up a broken FRG-7700 the other day on ebay.  The florescent 
display tube was indeed cracked and I doubt I can find a replacement 
sans another bad FRG-7700.  The only other problem was a defective cmos 
to ttl converter chip.  Without beating a dead horse, my thoughts are to 
tune the receiver to 455KHz and use the radio as a ssb converter 
appliance  Any comments? ... tom, N3LLL
