Thanks for all your replies.
Adding an extra level of folders is asking for trouble.
My bad - I wouldn't actually be adding another layer of folders - it was the only example I could think of at the time.
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".
As you say, I was considering these changes due to Panda. I also do have weak content on a large percentage of site, but have some great content too.
I was just thinking of a re-structure etc before I embark on a major content writing mission. On reflection, I think I had my priorities wrong and will concentrate on the content first.
