Have you downloaded Mark Porters plans? He calls out 6mm for some parts, .8mm for others. If you use 4mm then you will be heavy where the .8mm parts are, but can probably get away with replacing the 6mm with 4mm. You will probalby require larger motors for the craft to operate the way it should is you use all 4mm ply. Lightness is a key to hovercraft performance (both models and full scale), so, like an airplane, the lighter the better.
