That sounds very similar to what this fellow has done, only it seems his FM converter is scratch-built. The video has subtitles but a lot of information gets lost in translation.

Ultimately this sort of thing is what I would like to do, a totally reversible "barely there" modification. I was thinking I might be able to do it with a modified automotive FM converter, but then MadMan mentioned the FM portable radio which would be much easier to get my hands on.
