everyone has a different idea, i suppose, as to what is 'appropriate' - or 'classic.' of course, you are being somewhat avante garde by putting them out of order in terms of composer's lives. i only put mine mildly out of order (the prokofiev. but it was before intermission). i am really just 'winging it.' as i see it - the true way to figure out a program is to experiment with many pieces in many orders.
take them and actually listen to the program in that order. if something seems not quite right - it could be due to too sudden change or not enough change of one style to another. i tend to like the slightly gradual change of style (say from bach to beethoven). now, beethoven to prokofiev might be a style change based on rhythm instead of form (or even a bit of form and rhythm connection. after all- it is a sonata).
the ligeti - well, i'm a complete baby about him - but i see that stravinsky was chosen and ligeti seems to follow the stravinsky idea in his own way doesn't he? clean lines?
ending with a passacagli is bringing a cycle idea into the thing (from baroque to modern composition with baroque form). and the couperin finish is just saying - here - take a bit of a whistle with you.
