I wonder if Balsa wood would be suitable?  Like polystyrene foam, 
only stronger and easy to glue.

I think commercial OXCOs use polystyrene foam that's expanded to 
shape, which is fine in production, but making the mold for one use 
is not efficient.  However, there are lots of expand-in-place 
urethane foams available from building supply houses.
