Trait concept, Not sure if this is a "cheap idea" or not.

[Tumuel]

Basically, I'm thinking of a trait (not sure what it would be called) that basically does nothing until you install a bionic.
You'd have a chance (50-50?) of becoming either a prosthophile or a prosthophobe.
The reason I think it would be a good idea is that whenever I see a tribal with either prosthophile or prosthophobe I find it very distracting, because tribals probably wouldn't have too much experience with prosthesis.
