Cross cutting would reduce the amount of surface area, and that would reduce performance.
Try optimizing the flow instead.

As pH pointed out I think your mixing up surface area with overall mass. Seems to me there would be more surface area (just a guess no math involved) and less mass with his revision.
What I would do is widen the channels a little. I think the fins are to wide leaving a warm area in the middle. To maximize the fins you want to make them wide enough that the water can absorb (for lack of a better term) the heat half way through the fin on both sides. That makes it 100% efficent. If the fin is to wide and the water can not absord the heat through the entire fin then that is not 100% efficent. Also you don't want the fin to narrow either as then the heat will not travel up the fins and shed into the water as effectivly as it could be. This is (IMO) one of the reasons the White Water works so well. He made an exellent balance of fin height and width and with the jet impingment made it as efficent as he could.
