PE
perhaps an interlayer of polydimethylsiloxane (polyvinylacetate) between the support and the silanized PVA could work?
I can tell from first-hand experience that styrofoam (or another non-cellulose but porous material) could be easily glued together with PVA or PVAc wood glue
maybe the subbed support has just the right surface texture.....
