I've seen this done successfully, but it used a regular FRS unit, a headset and a Vietnam era reciever. The FRS unit is located out of site (in your case it would be the radio bag and the headset is disassembled and placed in the Vietnam era reciever. It looked pretty good and operated rather well too.

I beleive the folks at In Country know what I'm talking about. George from Winterpeg did it, was cool to see him using it with-in his squad.
