The worst thing that can happen is if your heir comes of age as something like a unit of Yari Ashigaru, Nodachi, Samurai Archers or Yari Cavalry - as these units are too front line or vulnerable. If it comes down to it, I would go with Naginta or Yari Samurai heir units as a second choice as at least they're quite defensive.
This is a bit off-topic, but I'm curious: Has anyone ever trained no units at all when an heir comes of age? And if so, what happens? Does the heir appear anyway, or does he not show up on the map at all until you've trained another unit?

Having never tried it myself (I do my best to have a company of HC/CA/YS ready as my heir's personal unit), I've no idea how this works.
