Hi, It will use the non-retina 32x32 for 16x16@2x, etc, so your icons will not look pixelated if you omit the @2x icons.
If you're worried about the file size of your .icns file exploding, I've created a small utility that can be used in combination with png utilities like pngquant to reduce the file size of the images contained in your .icns file: https://github.com/avl7771/createicns/.
