The delamination is due to stress in the layers being unequal and failure of the glue with drying out. The ply started out flat and was steamed and soaked until it became pliable, bent around a former and left to dry.

Taking this as correct, if you get the plywood damp through the layers with dilute wood glue, pva, and maintain the correct shape whilst cramping the layers together, it will hold its shape once dried out again.

So I think you have to be brave. Cover the outside veneer with cling film that will not take pva and soak the whole thing right through with well diluted pva and deionized water.
Arrange as many clamps and formers as possible to hold the correct shape and leave it many days to dry.
