My goal is to get into Juilliard, graduate, and play in the New York Philharmonic (see details)?

If I want to go to Julliard, then when i graduate play in the New York Phil Harmonic, what would be a good instrument to become very good at? I want to play clical. I currenlty play clairnet, b clairnet and piano. I decided no piano since it is the most popular instrument therefore making it very hard to succeed in since everyone else is alot better. I was thinking b clairnet or should I try a complete new instrument? Help please!
