Yes.

I was thinking cut up a silicone baking mat:

A couple aluminum plates, some stove heating elements using "photonic energy transfer", I.E., radiant heat transfer, some thermistors to sense the heat, a couple comparators, and two $8 solid state relays from Surplus Center.

All of which I have in the junk pile.

Simple way to apply the pressure would be four spring loaded wing nuts, one in each corner. Maybe in slots for easy removal. 

Other methods come to mind as well. Halogen bulbs pr lights for the heat source, cheap Chinese arbor press for the pressure.
