That’s not really how it would work.

If you want that outcome, it’s better to train on as massive a data set as possible initially (which does regress towards the mean but also manages to pick up remarkable capabilities and relationships around abstract concepts), and then use fine tuning to bias it back towards an exceptional result.

If you only trained it on those works, it would suck at pretty much everything except specifically completing those specific works with those specific characters. It wouldn’t model what the concerns of a prince in general were, but instead model that a prince either wants to murder his mother (Macbeth) or fuck her (Oedipus).
