Hi,
So: Anyone knows a some history of unfulfilled romance where the characters "turn into the souls" of each other over the centuries?

I will be very grateful.. :-)

You can try reading Remembrance by Jude Deveraux, She-Who-Loves-Silence by Henry Fairfax and Juliet Immortal by Stacey Jay. These are not exactly what you were looking for but are pretty interesting
