It wouldn't surprise me to find that Les Paul may have done some early stereo. It's something I may be able to look into if no one else has any info. After all, he also operated recording studios in CA and Long Island and had lots of early stereo-possible recording equipment.

The Mendelssohn MSND music that was paired on LP with the Schubert WAS issued on a two-track stereo tape, though, so the stereo versions were likely more than the mere figment of someone's imagination; they probably existed at one time.
