You could try the Godowsky transcriptions of Chopin Etudes.
For other left hand pieces, here is Moszkowski's etude op. 92 no. 12, written specifically for just the left hand. I suppose Scriabin's Nocturne for left hand would also be fun to play.

...so should I do the Rachmaninoff Prelude Op.23 No.2 or the Rachmaninoff Moment Musicaux Op.16 No.4?
You need to sort out your spacing here - it looks very confusing! That said, there's certainly some useful and intersing material here - and, while we're about it, don't let's forget the Wittgenstein arrangement for left hand of a certain transcription of certain music from Tristan und Isolde!...Best,Alistair
There are now at least two threads devoted to what Ives would have called "southpaw pitching"; perhaps they should be united (if not defeated!)...Best,Alistair
