Should I include written evaluations (from courses I took) in my transcript as part of the job application materials?
If your course evaluations range from good to excellent and there is nothing harmful in them, including them can only be helpful.

In the worst (and probably more likely case) people will simply not read the additional 10 pages of transcript. This is, of course, exactly where you would be if you didn't send them in the first place.

A thick application file is not a problem. Just remember that it falls on you to help narrate and explain what you include. For example, if there are a few choice quotes from the evaluations, you might want to call those out in your application front-matter.
