Instead of making the transparent areas fully transparent you'll

those areas.
Wow, really? There's no way to specify a (1-bit) mask for hit
detection, separate from an 8-bit alpha channel for opacity?
Short answer: No.
Long answer: There are no 1-bit masks for the thumbnail or larger
icons. You can do what you describe for smaller sizes, but if the
user is working with icons larger than 48x48 the Finder will be using
the 128x128 thumbnail icon scaled down, and that icon has no 1-bit mask.
