It's funny what people will consider an advanced piece. For instance, I've been working my butt off at the rep listed in my signature. The Ravel and Debussy are good, and the first movement of the Scriabin is going well too... however, that damn Rach etude is NUTS! Comparing it to the 2nd movement of the Scriabin, I find the Rach more devilish.
Maybe consider some short nasty pieces. You barely have time to get into them, and then they are over, along with your career (joking!). Chopin's b flat minor prelude, the E flat major, and his more technical etudes still *get to a lot of advanced musicians... obviously a large scale work is a challenge (Liszt sonata, Barber sonata, Rach sonata, a concerto, etc), but a group of short intense pieces can be just as daunting to practice.
I subbed out the Rach and switched to 'Pastorale' by Kapustin. I like conquering rhythmic challenges more than sheer velocity hurdles. The Rach worked at a slower pace, but I just got sick of fumbling

...maybe I'll come back to it.
Liszt études, Debussy études... Allegro de Concert by Chopin, most of the Rach études, Prokofiev sonatas... I can list about a thousand pieces off the top of my head.
