I wouldn't bother. Instead get yourself a light-ish aluminium rear rim and a disc cover. That will be more aero, and unless you're going uphill at <10mph the weight makes less difference than the aero. Plus down any hill you will ride much faster because you will be confident that the brakes work properly.

If you really want to go faster, either invest in some proven technology (much cheaper than a crash) or do some stretching, pilates and so on until you can get a few cm lower. Then you really will go significantly faster than bolt-on upgrades permit.
