Asparagus in a very large planter box?

I'm thrilled to be living in the woods. But I have very few places to plant sun plants that aren't watered by the septic spray heads. (The water is fully treated before being released, but still...) We will be building several large planter boxes on the deck for vegetables. Would it be possible to grow asparagus this way?

Most of my beds won't be much more than a foot deep, but I could make one bed deeper for asparagus. I know they like to grow long roots. I could also place my crowns a foot or more in from the edge to help protect them from freeze. Most beds will be about 4 feet wide, though if I placed the asparagus next to the house I'd probably make that bed 2 or 3 feet wide.

Any thoughts on whether this might be successful? What soil depth would you recommend for the planter box? While I've read a lot about it, I've never grown asparagus before.
