I've used double sided foam tape + aluminum foil (yes the kind used for
food) with a bit of scotch tape over the foil to prevent shorting in
repairing Lisa keyboards. Worked just nicely once they were cut to the
right circular shape. Yes, the key feel was off after that, but livable.

I could use a few sets.
They are <relatively> easily self manufactured. As long as
you aren't picky about the keyboard "feel" any foam will do.
I use a sharpened tube that fits into my IDC crimper along
with a small piece of wood as a punch for the mylar and foam.
I reuse the existing rigid plastic disks... the old foam and
adhesive easily rubs off. It takes me about 1 minute per
key.
