I think your right in the dead of winter, the lakes around here, at least, are about the same temperature all the way down. Except for the ice on top. In the summer of course, temperature varies with depth.
NeilBlanchard, that diagonal well idea would simplify the manifolding.
I like the closed loop systems, I think open loop is what gave geothermal a bad rap. Any time something is going to save you money, everyone else wants a piece of the savings. For some reason some HVAC installers think they are suppose to make more money on a geothermal system than an air to air. But then down at the diner during lunch, I hear how easy it was to install the geothermal in their own house.
