I agree with arda, I think the Liebestraum fits extremely well into the program, especially as a second part. Remember that there are also two other Liebestrams that don't get played nearly as often!!! I would also recommend taking a look at some of the pieces from the second Years of Pilgrimage book, some of them are really beautiful and not played as much as the Liebestraum--for instance take a look at the Sonnets de Petrarcha (but stay far away from the Dante Sonata, that one would not fit in your program at all).
