I would have doubts about foil being part of any robust long term solution, can someone point to where it has been used successfully?
Re the cooled base idea, if you were to attach the camera to a broad cold finger platform that is cooled by the TEC that should cool the camera body pretty effectively. The copper/alumnium cold finger platform that I have from a laptop can be bent to serve as a base for the camera - screwed to it via the tripod mount. A box of thin foam can then surround for insulation. It may not be as effectve as an internal cold finger on the sensor but you would not have to mod the camera in any way.
