Perhaps you could scrape https://nytbee.com/ https://nytbee.com/, mentioned in the thread, for the historical answers, or contact the owner. Also @banana_giraffe, a commenter on this thread, seems to have scraped 6 years of data. Then you could take a very permissive wordlist and filter it using the historical data. For all words of six distinct letters or fewer, you could determine whether they were allowed, not allowed, or indeterminate (no puzzle ever appeared that would have allowed them). My gut feeling is that you'd be left with very few indeterminate words, though jouk and qajaq might well be among them - review those manually.
