Second-best idea... I've seen older datasheets for 74xx parts where they've put the image for the chip die *plan*. It always looks like it got copied on a cheap fax machine that had never ever been cleaned of toner -- but it's, you know, /there/.
Since what you want is a "representative" image -- put up the chip die plan for the most basic of configurations, without any extras, and *include in the image* a caption explaining that that's what it is -- the base configuration, and that said configuration can and will be customized later for individuals and companies with enough clout and MOQ.
