There's Johann's arm.
Not sure outside of that. (Not sure if 'get the Lizardmen to do it' is a viable strategy)
I was more thinking of whether there was anything from canon.
For another direction of radical transhumanism, find a swarm of the apparitions known as Flies of Nurgle that has the potential to become a familiar, bind them in the form of floating golden eyeballs, make them a familiar, and develop the Share Senses familiar trait. Then look through the eyes of the swarm. Useful not only to replace regular eyesight but with a host of potential, from 360 degree vision, to sending some of the swarm off to scout to being able to examine things from all sides at once, depending on whether you can adapt to process the sensory information.
Depending on the nature of an Apparition's senses, might also allow accessing a different form of Witchsight.
What could go wrong!
Edit: an alternative option would be to see if the elves know how to control the process of creating an artificial familiar more precisely to get a desired result and know how to work with a familiar to control what traits you get. Then, surgically remove the Chamon saturated eyes and use them to make a a pair of artificial familiars before reimplanting them.
