Oh, it’s happened before. I’ve seen players attempt everything from the purely mechanical Furiosa Special,

to the more advanced Orky variety with pneumatic pumps and sometimes even electronics!

There are OldTech cybernetic enhancements one can acquire, though those are not only exceedingly rare, but also stupidly complex to install in a living person that isn’t a pure strain human and also wants to survive the procedure. If a group of adventurers are fortunate enough to plunder an ancient medical facility that also still has power, working systems, and maybe a friendly AI to boot, cybernetic augmentation may be possible!
