Are you sure the wall is a real brick veneer or is it a thicker bonded structural wall of clay tile and brick? Are you sure the clay tile "bricks" are only 4" thick?
Are your current heating costs out of line, assuming you have done whatever is necessary for the roof and window caulking?
I had a magnificent masonry home (built in 1917) in St. Paul, Minnesota that was 10" clay tile/block with stucco and they were common in the more prosperous areas (especially with European immigrants, since wood was sign of inferior construction) because of the permanence and reasonable energy cost and superior comfort. My home had a newer gas fired circulating boiler that ran once or twice a day because of the thermal inertial of the walls and the cast iron radiators. - It was sized by HVAC contractor that did not understand the benefits of thermal mass.
If you use the correct adhesives there should be no problem. If you are paranoid and influenced by the pink panther, who is afraid of moisture and real insulation properties, there are ways to sooth that mania. The air gaps to separate a proven exterior wall from the interior are necessary because the thermal and moisture conditions are different that you consider for shoddy lightweight construction.
