Dust collection on a router table and a template guide?

I have a box built around my router with a 4" hose going to it. The last time I routed with a template guide the restricted air flow got my router hot enough to fry an egg on. It didn't hurt anything, but obviously isn't something I want to do again. I can open the box to allow airflow, but then I won't get any dust collection. But of course there won't be much dust collection through the template guide anyhow.

I am thinking about drilling some 1/2" holes in the Woodpecker plate that holds the template guide and leaving the box closed. I figure that will allow airflow and catch at least some of the dust. It seems like a good thing to do, but they don't make it that way; maybe there is a good reason for not doing it that I am overlooking.

Any ideas?

I bought a Leigh RTL400 6 months ago and am finally going to give it a try.
