Go for it. You’ll figure it out yourself whether you can or can’t do it. Don’t listen to anyone who tells you you can or can’t do something
This guy right here understands it. There are literally users on this website (though they're long gone by now) whom managed to learn works like Chopin's op. 23 after only playing the piano for two years - though they're extremely talented.Point of learning and playing music is all about experimentation. Experiment and see what you're capable of. If you fail, no big deal, just leave it alone and learn it sometime in the future. To be fair though I was initially self taught and did some "jumps" as well, but there were nowhere near as drastic as yours. I think my most difficult pieces within the first 2 years were Chopin nocturnes and 2 Rachmaninoff preludes. Going from those pieces to the op 5 is a BIG jump. Rondo a la mazur is a piece I attempted and successfully performed in public about 5 years or so into playing piano. And I had a good deal of difficult pieces (Chopin's polonaises for example) under my belt by then. Learning it was difficult even with the help of a teacher. It's a bravado piece so you'll need to be well acquainted with the instrument to actually learn it. The piece utilizes the piano's entire geography (none of the pieces you listed have that feature), you have to be comfortable with an array arpeggios in several keys, comfortable with quick descending runs on your left hand, descending minor double thirds (the piece is in vivace mind you), large chords - pretty much everything in the piece you'll be encountering for the first time. I don't think it's feasible to be introduced to all of that in a piece as difficult and as long as this (it's like what, 12 pages long?). There's a good chance it'll kill your motivation for the instrument, because you'll spend a long time trying to learn it. If I was a teacher I'd advise against it and tell you learn a nocturne or something, but like I said there are people here who learned balldes within 2 years of playing the instrument. You might be one of those freaks, so why not go ahead and try it out?Good luck!
I'm one of those who'd advice against learning things too far beyond your ability. Why? Because it easily establishes bad habits if you try to force something you are struggling with to work. I was one of those people who started tackling a bunch of pieces far beyond my level at one point during my piano studies. I was reckless, and I think a bit arrogant, and wanted to hurry along to the pieces I liked. It worked, sort of, until it didn't and I got riddled with pain and poor technical habits for years. That's why I would warn against tackling things far beyond your level without expert guidance.
Everyone will go through this ego phase bc of human nature (some don’t grow out of it). For most we eventually hit that stagnant wall bc of missing those core fundamental skills. As long as we recognize it and learn to change course it’s normal. The OP is smart enough to even ask this question to acknowledge the problem. There are many out there who don’t see the problem of mismatching skills.
I get that. But if it at all possible, I think it's better to acquire those core fundamental skills at the beginning, and not after the fact. It will save people a lot of frustration and grief and wasted years
