Please no, those Chopin pieces are played to death and a lot of people will die a little inside :/
Okay, a little over exaggerated... But seriously.
If you want Chopin, go for some of the easier nocturnes- you could do the Op 32 nocturnes. They'd be a nice piece of recital material, the two (B major and A flat major).
For classical, I'll recommend the Mozart Fantasy K. 397
