The important thing is to keep the axial stiffness more or less identical to the current plastic chassis!!
IMHO the plastic chassised cars are BETTER than a CF chassis / tub as they tend to flex a little more.
That said the AC S4 / S44 tubs were far more flexible than I imagined they would be.
I'd not be interested in a flat chassis as no undertray is available for the FS. Lots of thought went in the chassis on the Mako I did a few years ago so we could get away with a chassis that was stiff enough along it's length but still had the correct level of axial stiffness.
