TWO dozen? Man, you're an optimist!I joke about Jakandor a lot, but I think producing a new book for it, unless they poured an enormous amount of resources into it, would be a guaranteed money loser. In fact, I think most of these defunct settings would be.
"I and my two dozen passionate friends would buy it!" isn't enough to sustain a "proper" book, even if there wasn't the opportunity cost of only being X number of slots on the production schedule -- which can be increased, to be sure, but not infinitely.
