Should I quit my PhD?
If it is impossible to compile a thesis from all your publications, I suggest focusing on lesser publications in the thesis and if it is possible to expand your work, focusing only in one direction. Since your work is already published, there is no reason why it wouldn't be accepted by the reviewers. The content of the thesis counts less in applying to post-doctoral jobs, what is important is your papers. Of course, the thesis must be well written, rigorously, etc. There are many people who receive PhD diploma with few publications, or even no publications at all.
