John,

Correct me if I am wrong but the designs that you and Wouter are presenting are still a tortured ply design, i.e. the side panels have curvature in more than one direction and so the ply sheet still has to be tortured i.e. bent in two directions at the same time. Although by keeping the amount of curvature in one of the directions small you are making the torturing process easier.

I don't think there is any way around this to produce the kind of hull shapes (which I think are good) that you are proposing

Does the software that either of you are using have the facility to produce flat panel patterns for the side panels that you are designing?
