Foam pads were used in at least one brand of blank cassette tapes (3M AV
series is what I*ve encountered, and they deteriorated into dust that
contaminated the entire cassette tape.  Foam in general doesn*t age well,
in my experience, so I would recommend sticking with felt pads.

Rehousing cassettes is an excellent practice to insure a longer lifetime
for the original object and to guarantee the best possible low friction
transfer.  Even cassettes without screws (sonically welded cassettes) are
not that hard to open, especially if you follow Richard Hess* advice and
use a pair of circlip pliers, where the jaws spread apart as you squeeze
the handles together. I like to start at the rear of the cassette, at the
breakout record/tape type tabs.  Sometimes it*s a bit of a messy process,
but it*s always worth the bother’
