If you have to ask whether you should play this piece, then you are not ready. Anyone who is ready to play pieces this calibre would have attained the capability to analyse and judge difficulty level of pieces on their own.
My hand size is a 9th comfortably, a 10th is just really painful, and i miss the keys 4 out of 5 times. Fortunately I don't think this piece ever goes beyond an octave reach. Though for a lot of the octaves I think I used my first and fourth fingers- particularly the second page.I think you are perfectly capable of playing this piece if you have patience and figure out a decent fingering.
this is a really fun piece (at least for me), but i lost interest in it. much easier is the prelude in c sharp minor and maybe playing the last part of the c sharp minor at much faster than tempo could be good prep for the g minor
You are probably ready to handle this piece, if you approach it from the right direction. Your main concern of injury is a velid one - when you practice this, pay attention most of all to any tension you might have while playing very slowly. This tension, when you increase tempo, will make it impossible to play the piece well. But if you don't rush things, and carefully analyze the fatigue you feel when you play the piece (and change fingerings/relaxation accordingly), you would certainly be able to handle it.Good luck!- Motrax
In my opinion, the rhythm of this piece is extremely simple to understand
