Sounds like an exploit waiting to happen, though...

AFAIK there’s one more step: You need to set the “custom icon” bit on the .app directory (e.g. using the SetFile command line tool). But yeah, as this is something a user can do on the app in Finder, all this needs is permissions. No leaving a huge gap in your signature (or leaving it away completely — don’t even think about signing again on the user’s machine, that defeats the whole purpose of code signing).
But anyway, NSWorkspace has a method for adding custom icons to a file: -setIcon:forFile:options: that would probably be the most convenient to use.
