The thesis is probably pass/fail, so I would just be happy and move the thing along.
I recommend to take the attitude that you are the "captain of the ship". If you are doing a good job it shouldn't matter about the advisor. Consider how you would just write an article as solo author to send to a journal. It would be your baby. This doesn't mean not to consider feedback, but I recommend to take the attitude of a Hollywood director, you make the final decissions--great art does not come from committee reports.
My point is that if you are doing a top notch job, it is not the end of the world that you are not getting close readings. Sure, in a world of unlimited time, that would be great to get. But your advisor has to prioritize and may have other students that are struggling, work of his own, etc.
In terms of publication, I would worry about that when you get to that. You may have minor or major transformation required to turn it into journal articles. But deal with that when you are in that, versus trying to make a thesis match exactly a journal article. There are some logical differences of the two. For example longer lit review is normal in a thesis. Or you may show some incomplete work (so at least it is memorialized somehow) or have small innovations in apparatus or methods to share with your future lab group mates. If you are just publishing a monograph, that is a little different, but I would still lean towards just letting that be the thesis itself (this is different in history/lit if you actually go through a book publisher).
Finally, just push the thing along and move on to other work. There is so much to do in the world and master's theses are rarely read. Still do "good work" always. But just try to get this project done and move on to new research. You sound like you are capable of good things.
