You could try adapting/converting 'Torn Asunder: Critical Hits' (a 3e supplement from Bastion Press) to 4e. I'm not sure how easy that would be (not a 4e player) but I imagine it wouldn't be too hard, really.
Great book, anyhow, and it might give you some ideas, if nothing else. It covers detailed critical hits, called shots, and a number of other related things.
Indeed. Converting to 4e wouldn't really be that much of a stretch for Torn Asunder.
Incidentally, you can find the print version on sale here: Studio 2 Publishing, Inc.
