Why not consider some lesser-known Baroque repertoire instead of another Bach P&F? Everyone hears the latter so frequently, especially professors and jurors. Rameau, Couperin, Byrd, Buxtehude, Royer, the list goes on! As you said, you need some FRESH thoughts.
You are more likely to shine in repertoire that is well-chosen according to your individual strenghts from the vast amount of lesser-known-but-still-first-rate repertoire. This is for two reasons. The really well-known works by mainstream composers are played all the time by students who don't handle them nearly as well as the few top-drawer professionals who really do play that repertoire well.
As an aspiring artist, one can benefit greatly from playing a piece which we haven't all heard (and played) hundreds of times. Imagine if I were on your audition panel, and you were playing a programme filled with stuff that I myself have played countless times in concert. I'm going to have quite a well-evolved expectation for that music, subconsciously, and chances are your rendition will not live up to those highly-critical expectations.
If you are playing a number of seldom-heard jewels by under-recognized composers, I would be more likely to take a shine to you. Chances are high that I will not have played the particular works you have chosen. Compared to, say, if you've chosen the G minor Ballade, and I've heard 10 Chopin Ballade no. 1's in the last two weeks judging a competition. You happen to be auditioning one fine Monday morning at 9 am with the 11th, and I probably have very specific taste in this piece as I myself have played it many times and recorded it.
