For the cost (in time) to figure this out, you could be running any number of chips already.
Whats the point ???

Unless they have a window in the top, they're not reprogrammable. Finding reprogrammable ones in a keyboard is very rare. And even if they are, you still have to find software and a programmer. And someone to help.
You can get free samples of most any current chip. Save yourself the hassle and learn a skill that you can use on current technology. mike
