But much easier damaged than the 6mm mdf.
'Foamex' type foam board should be tough enough. You would generally use
a sacrificial spoil board over it anyway.

The product I linked to is basically shellac in a can.
I used it for sealing MDF foundry patterns with very satisfactory results.

Yes, but having painted MDF before, it requires a particular sealer, then
several coats of paint, which is a bit of a pain. So its a method which is
lower in material cost than, say aluminium, but
I really like that idea. Getting the slope and pocket dimensions just
right would take some experimentation but if it works it would save a
lot of hassle. I dunno if MDF would work as a top plate though. That
stuff leaks like a sieve, especially if you cut through the outer skin.
I use 6mm MDF
