Bevan,
A flat top to the diffuser is fine. Actually better in that it will not be as sensitive to pitch changes.
A curved diffuser will produce greater low pressure, but only with a wing that is designed in conjunction with it.
They are very critical in shape and the only folks using them are the F1 guys. And they have wings and diffusers as matched sets. One does not work without the other.
