The keyword in the URL isn't the main objective
What is the main objective?
Quite often, particularly post-Panda, when I see people doing something "for SEO", it's because they've lost rankings and, as often as not, that's because their content is weak. That can also be reflected in their backlinks. In this case, it sounds like you're not ranking for "widgets".
Not to take the thread off topic, what else does the re-structuring involve? What prompted it, and what else are you trying?
