Don't even think about it. It's a bodge of the first order and you'll
regret it.

I can't see anything wrong with bonding slates together from below but
that wouldn't involve covering the whole surface with foam. A couple of
lines of foam between each joist would probably be sufficient, and
that's an easy d-i-y job. It would make the slates unuseable in the
event of a refit though

Not very easy to stick to the underneath of a dirty flaky old slate.
