It works on embeddings, which are concepts. So it would at least be manipulating a similarly weighted network of concepts, though much shallower. It would be an answer from his literal domain of discourse. It would be evocative rather than authoritative.
What you describe would be literally worse than nothing. The use of those concepts would make about as much sense as the use of topological concepts in a Lacanian text. A typewriting monkey in a trenchcoat.
For a possibly not useless proxy, train an LLM on his oeuvre and ask it.
