with the lower nose mandated the cof Gof the legs is going to come down ,the bum is as low as possible anyways so you got some degrre of freedom with the drivers Torso...But more upright pushes the cockpit sides up ,as those need to meet the helmet.Wich leads to a larger crossection as the shoulders are higher up ...can you make use of the space gained .i´m not sure..the Mclaren with the low front and low low drivers back is worth a look.
I think they will narrow the tub a bit revert to the low slung steering rack and reposition kers components.Elongating the car a bit at the rear .Unfortunatelly they seem to hav lost their expertise with cf-gearbox casings (Gary Savage not there anymore),so maybe having a very integrated solution in aluminium is a bit difficult.
