Dear Mr. Mister:
I like your alternatives: wonderful pieces, all of them. However, let me share a principle of mine when choosing new repertory: you just played Beethoven, Mendelssohn, Ravel, and Rachmaninoff. Beethoven is something you must always play, but about the others, why not to change? If you played Mendelssohn, do some Chopin or Schumann; instead of Rach, play Tchaikovsky; and to Ravel, the obvious alternative is Debussy. Notice that I like the composers I'm telling you not to play, Ravel in special, but that's not about someone's likes and dislikes: is about a wide and deep knowledge of the main repertory, which you'll never have playing always the same composers.
By the way, you will not play some Bach? And some 20th century music?
Hope it helps. Best wishes!
