A lot of modern scores are written with MIDI in mind (whether or not the composer knows it - that's how they hear it the first 50 or so times). That should make it somewhat easier to go MIDI -> score for similar pieces. Current attempts I have seen still make a lot of stupid errors like making note durations too precise and spelling accidentals badly. There's probably still a lot of low-hanging fruit.

This is absolutely not easy, though, given all the cultural context. Things like picking up a "legato" or "cantabile" marking and choosing an accent vs a dagger or a marcato mark are going to be very difficult no matter what.
