Technically you could use noindex,follow to keep link juice, if that's a big concern.
If these pages aren't mission critical, I would just open all the pages, and see how aggregate traffic is affected, after say, one month. If the main page drives more traffic than the individuals + main page, revert back. If traffic increases overall, keep monitoring. Also keep monitoring indexation, if one of the individual pages is kicked out, sure fire sign that they won't get traffic.
