Thank you.
If the pages are low PR, sometimes Google maske a quick decision based on title and meta description - so ensure that each page has a unique title and description that is quite specific to the page content.
Not to say that rewriting the url can't be a "somewhat" helpful step for ranking. But make sure the essential on-page factors are handled first, or you're not likely to see much reward for your troubles. in fact, you might accidentally cause more troubles if there are technical errors that allow duplicate urls to resolve to the same content.
One last thing - are you talking about omitted results in the in site: operator search, or in a regular search?
If you currently get almost no traffic anyway, then you've got little to lose by putting in a url rewriting scheme right now as well. Just make sure that you "nail it" technically and don't allow more than one url to resolve with a 200 http status for the same content.
