Subject: How to super harden papers?

I am fixing out some photographic papers for use as carbon final
supports but after fixing and drying the gelatin surface is a little
soft for my specific application, even with the addition of a small
bottle of the potassium alum hardener that comes with Kodak Rapid-Fix.

My thinking is that the gelatin might harden more with the addition
of some formalin or glyoxal to the fixer. Does anyone know if this
might work, and if so, have a general guide as to how much to add per
liter of fixer?

   Why not a suplementary Chrome alum hardener?
