If your area is as humid as mine is, NC, then one potential problem i see is humidity in the house. Lowering the temps via a heat sink would also bring up the relative humidity in the air, at least that the way i see it. where I live lowering the humidity is often as important as lowering the temps. When you are at 72 degrees and 90% humidity it's amazing how hot the air "feels" and how much cooler it feels if you simply lower the humidity. a more efficient Air conditioner would probably be much easier and cheaper than all the changes you are thinking of making. where I live it's already far to hot to be comfortable, especially at night, with out the AC. We are so humid that even in the winter when the temps are in the low 70's or hight 60's you can sit and sweat. turning on the AC and lowering the temps by 1 degree will make a huge difference because the AC removes much of the humidity as it lowers the temp. You set up would lower the temp but it wouldn't remove much humidity, An AC is very good at removing humidity due to the high temperature gradient in the unit. Your heat sink wouldn't have a big enough temperature gradient to remove much humidity, a dehumidifier might make a difference on your idea but then you would be using power to run the dehumidifier, not sure if it would pay to do both as opposed to just having an efficient AC.
