BTStack on ATV2 with hearing aid?

I guess this is a long shot but I thought I’d ask…

I know the BTStack’s primary purpose is to pair with BT keyboards and mice, but does anyone know if it might be possible to pair. and then channel the audio through, to a Bluetooth hearing aid? I have a profoundly deaf friend with such a device and it would be incredibly useful for her for non-subtitled movies, which is almost all of them on the iTunes store…

Thanks for any help!
