If you enjoyed the Mozart Fantasie you might like to try the Rondo in A min Op 511. I managed it with similar handspan.
Mozart sonata A min K310, F maj K332.
For ideas I usually look on exam repertoire lists of the various boards for G8 or first diploma, or TCL advanced cert, listen on the Tube and see if I can check out the piece for doability on IMSLP. Smallish hands are a nuisance for a lot of the more advanced rep though, in my incompetent experience.
Another way of trying to up your stamina is to choose a set of pieces from a composer you like, and make a programme of three or four contrasting ones from it to perform consecutively, maybe say from Janacek On an Overgrown Path, Debussy Preludes or Dr Gradus, Bartok, Mendelssohn SWW ... endless possibilites.
