I know there's a clever title out there somewhere waiting for me to stumble upon it.
The music is decided already, though - works in the style of (or in deep homage to) other composers...
Debussy [Czerny], Dr Gradus ad Parnassum and No. 1 (pour les 'cinq doigts') from the Douze Etudes.
Grieg [Gade], Lyric Pieces, Op. 57, No. 2, 'Gade'.
Howells [Finzi], 'Finzi's Rest' from Howells' Clavicord.
Schumann, 'Chopin' and 'Paganini' from Carnaval, Op. 9.
Barber [Field], Nocturne, Op. 33.
Ravel [Borodin], A la maniere de Borodine: Valse
PDQ Bach [you name it], Prelude and Fugues from The Short-Tempered Clavier.
