Interesting idea. My only thought would be you might have a surface area issue after the first cycle. My recollection is the calcium chloride comes in granular form from the sources you mentioned. It turns to a liquid upon absorbing lots of water, and I'd guess will form a solid cake on the container it is in when it dries. Having less surface area will slow the expulsion and absorption of water I'd guess. Not sure if it'd be an issue or not.

I do remember from one of the places I worked that had a very large air compressor that it ran through a large air dryer. It was comprised of two cylinders that were cycled (absorbing, then heated and vented to dry the desiccant). I tend to recall that they were filled with the silica gel desiccant. While I don't think this absorbs as much water, it also doesn't change shape/surface area.
