There is no problem getting rubberized cloth made to any specifications,
other than economic factors.  A while ago I found a company that coats
fabric and they said it was no problem to coat pretty much anything with
anything and with all sorts of different processes for applying and
curing.

The problem is that you need to buy tons of the stuff.  I forget the
minimum quoted but it was considerable.  Silicone rubber coated silk
would be fun to have made.
