if it was trained on a sufficient amount of fan art made in the studio Ghibli style and tagged as such, yes.

otherwise those would just be unknown words, same as asking an artist to do that without any examples.

though I am curious how performance would differ between training on only actual studio Ghibli art, only fan art, or a mix. Maybe the fan art could convey what we expect 'studio Ghibli style' to be even more, whereas actual art from them could have other similarities that that tag conveys.
