I wouldn't bother trying to make something like that for a few reasons. first, pelts need a lot of clamping to the block in order to be efficient, so planning something that close would be very tricky. also, the metal attached to the hot and cold (comparatively) sides of the pelt should NOT be in contact, that will allow heat from the hot side to travel around to the cold side. kinda like a short circuit, not a good thing. overall, even if the pelt were integral, there would still be the need for condensation prevention (i think) well, that's just my initial reaction to the design, anyone else wanna chime in here?
*edit* the internal design of a waterblock is always a factor, but with a pelt it is spread out (unlike a WW type block, which is focused over the core), and there is a lot more heat so its easier for the water to pick it up.
