Larry, I would think that, too, if I were convinced that such a thing did not cost an arm, a leg, an FCC license and a bucket of giblets.
I have actually done this using a car stereo modulator*. These usually come with a switch allowing selection of one of two frequencies near the bottom of the FM band, but I am just not sure that these are good enough in enough markets (i.e. with no interfering stations) for a stereo receiver to cleanly receive the signal.
And if it does, then you have a wireless link that goes, what, twenty feet? Then you have to have a stereo or ProLogic component back there with wires to the speakers. This could solve some logistical problems, but is sort of on the complicated side.
*I hooked this up to a super mamma-jamma antenna amp one day, and fed it to a full-wave circular antenna I had made. It nicely, illegally, gave me about a quarter mile range. Now, THAT is REAR channel!
