No,
I don't think so.
Astronomical telescopes are single aperture but they are usually not very wide. Microscope lenses are also single aperture but they used to have astronomic cost.
It is possible to make lenses that perform optimally at maximum aperture, it is just very expensive. They used to say that a perfect lens is diffraction limited. I have never heard of a photographic lens that was diffraction limited below f/4.
It is not possible to "pimp out" a lens. One exception is to use a band pass filter, that can reduce/eliminate chromatic aberration. A simple case is a green filter on a monochrome sensor.
The best lens at 135/2 you can buy is probably the Carl Zeiss Apo Sonnar T* 2/135.
It improves very slightly when stopped down to f/4, but performs essentially near optimum at f/2.

As a small comment to Simon and Slobodan, there are quite a few lenses that are very sharp at full opening, but almost all improve a bit when stopped down.

I expect not, but I'll ask anyway. Is it possible to have a lens customized so that it is sharpest wide open? If so, why are there no specialized lenses sold that are geared only for wide open use? I certainly would buy such a lens. I guess physics won't allow for it. I would love to have my 135mm f2 hot rodded.
