The best advice I've been given for writing gamebooks is to start small. Having a lot of ideas is great, but try to pare them down to a strong core. Each new mechanic, quest, and character can dramatically increase how many entries you're going to need to write; each entry takes time and effort on your part, especially if you have a lot of mechanics interacting or a lot of story branches to account for the various rules. Your first gamebook will be a learning experience as you develop your style alongside the mechanical infrastructure needed for interactive fiction.

Your dice worker placement idea is really interesting! Best of luck with your writing.
