Might be more realistic to just take a few inches off my limbs.
Have a steel frame made. You'll be much faster on a round-tubed steel bike that fits very well than on an ill-fitting superbike.
Why? Because your body is the engine and an ill-fitting bike won't let your engine perform optimally. Also, because your body is 90% of the aerodynamic drag. So, optimizing your fit optimizes your aerodynamics.
You may go through a 2 or 3 frames over a couple of years until you find the perfect geometry for you. Then, if you want, spend big money on a carbon bike that has those dimensions.
