All you need to do is match the refractive index and colour transmission and the rendering will be the same. Glass to do it is available, particularly in China.

Manufacturing the right kinds of flint glass is not illegal in China.

Old lenses are generally expensive due to rarity and high demand once they become ‘classic’.

The 8 element Summicron is a lovely lens and a modern reproduction would be great.

We often see threads here where members plead for someone to remanufacture Neopan 1600 or some other discontinued modern film. Making a copy of a modern film is incredibly complex, impossibly so. Building a reproduction lens isn’t exactly simple, but it is entirely achievable.
