Duet?

I've been writing and rehearsing my tune for a few weeks now and have recorded it a number of times in different styles but it's finished up as an unedited live performance of solo piano. I might do a few more takes and try and introduce a few more dynamics into the performance. I like the idea of the music being unaltered by the vocal recipient and potentially even challenging the vocalist to do a single vocal line in an unedited take as well? There are imperfections in my performance but I like that. This way the finished the piece would be like a live duet. Just an idea, I had fun approaching this track with a live feel in mind, might be nice to take the concept further.
