The answer is a resounding 'no'. Typesetting is something that is nearly completely done by InDesign at large shops — the advantages of LaTeX just aren't appreciable when laying out photo-heavy books that use layouts custom to each book. 99% of the things InDesign can do are definitely replicable in LaTeX, but it'd be a ton of work and would require one hell of a knowledge of LaTeX libraries. Contrast this with the fact that a competent high schooler with some knowledge of design can pump out great looking layouts with InDesign. LaTeX is great for personal documents and publications where layout has been wholly standardized, but those situations are quite rare for publishing firms.
