Patrick - Just curious. Can you measure the amount of total sideplay? Should be easy enough if you have a digital caliper. It's not clear from your description whether keys had bushings at some point or if the wood mortise that was originally precise has worn. I remember working with on old Erard action for which I had to use some extremely thin leather that was available through player piano supply. thought I can't remember whether that was for the keys or the repetitions.
