URL structure website

For as site I am working on I am combining news (blog) and events (Events Manager) on one single page. This because sometimes there won’t be that many events and an empty event page won’t look that attractive. Same goes for news.

I am combining the items in the loop and show 6 items on the frontpage and the rest on a page with the slug “news-events”

Since a custom post type and regular blog items can’t share the same slug I am wondering what the best URL’s would be for the events and the news items.

This is what I am thinking of:
Main page: http://site.com/news-events
News item: http://site.com/news/year/month/title
Event: http://site.com/events/year/month/title

Any pitfalls when going for this setup?
