I agree with Dragon. I provided a condensed version of my undergraduate thesis that had been edited (with particular attention to the required length). While my analysis and conclusions did not change, I certainly rewrote sentences that needed to be clarified. I haven't been in school for several years and that undergraduate paper did not accurately reflect my (much improved) writing style that has developed as I've matured and had broader work experience.
I said as much in a disclaimer at the beginning of the paper. It's worked out well so far.
