I think your word list is still considerably too large. Zero chance in my mind that jouk or qajaq, for example, would make it to the NYT wordlist. (I don't think they'd even be accepted in the crossword, which has looser standards, unless there was a very specific theme that called for them). Apart from being obscure, their only use seems to be as non-standard spellings, for juke and kayak respectively. The Spelling Bee doesn't even accept UK spellings.

At least 5 of the proposed pangrams wouldn't make the cut, either.
