Using the mylar from the balloons seems like the best of ideas.
It is very thin and would most likely work the best.
One could get a hole punch from an auto parts store ( used
for making gaskets ) and make new pads. I have closed cell
foam that is over 20 years old and still fine, unlike the
normal foam used elsewhere that ozone and time have turned
to a gooey mess.
I would say that this makes the keyboards repairable for
someone that want to take the time.
