Interesting. To me, only the “Minor Alchemy” at level 2 and the similar but more powerful “Major Transformation” variant of the level 14 ability (which latter I’m guessing probably won’t be relevant for the BG3 base game due to a level cap) look particularly problematic to translate to a video game. Were you thinking that others might also be difficult?
Not that some homebrewing might not be good to make the subclass more fun in BG3 even if/when it would be practically possible to implement its special features RAW, if folk think that would be needed.
With respect to how to homebrew those features I can see would be problematic, I like your idea of possibly doing something with surfaces.
