One of the easiest/cheapest ways to do it might be external post-tensioning. This can be done in such a way that it is virtually indistinguishable from piping.
Theoretically, all you would need to do is match the midspan moment in the original plank. You may find however that the moment capacity of the original plank did not have a big factor of safety after the topping was added. In that case, you might want to go a little higher with the external p-t moment.
