Maybe if you compared it to the cheapest 2x4 construction that would cost 1/4 the amount. If you spent even just half of the structural cost on a better wood design you can have offset 2x6s 12 inch spaced stud walls for an 8 inch thick wall space. I don't see how any masonry work no matter how low density could have better insulation values.
