... if you can get away with it. If your committee is fine with it, just write it directly as though it were a book. Skip the literature review, or make it something that you can simply remove with one click of the mouse. Address scholars in your field of study, making arguments that they will respond to. Don't waste your time with summaries of what everyone already knows. I finished my dissertation in 88 and published my book in 90. My wife did pretty much the same thing. Neither of us had to revise much at all from dissertation to book, because we both had publishable manuscripts all but ready.
All you are really saying is that you want to write a more readable, polished book rather than a typical academic snooze-fest. What you are doing is harder, of course, because you have to write work that is publishable, not just acceptable to a committee of 5. But it is also easier because you are streamlining your career.
Another piece of advice is to choose the hardest possible director, the one with the highest standards. The idea is not to get the PhD the easiest way possible, but to get a meaningful PhD, one that actually trains you to be a publishing scholar.
I've noticed students regressing from seminars to the dissertation, writing worse and becoming less interesting. Why? Because the Dissertation with a Capital D is so Intimidating. The big theoretical introduction; the overgrown 40-page chapters. Everyone complains about the same things, but for some reason they all perpetuate the system they hate.
People will tell you the dissertation does not have to perfect; don't sweat it so much, it's just something you have to do to get the degree etc... Those people are liars. Starting a second project as a beginning assistant professor is much harder than publishing the dissertation as a book. I've seen a lot of careers start off on shaky footing because the new professor cannot easily get publications out of the dissertation.
It may be that, despite your best efforts, the finished dissertation is still a long ways from a book. In that case, we can talk about that.
