The idea is to parallel the bio-mod system. The machines used to create biomods could be reskinned as a cybernetics fabricator where cyberneticists can design cosmetic cyberware. The resulting design is then fabricated on the machine into an installable object (named by the cyberneticist making it - similar to bio-mods).
Either a special tool can be created or this installable object can be linked to an existing install tool. Install then works like any chrome and the cosmetic cyberware would carry a PDS load just like a bio-mod does.
Once installed it works largely like a bio-mod. Nakeds are replaced as designed. The main difference is that this chrome, unlike bio-mods, is flagged so it is not retained after death. Pricing can be adjusted to account for all these factors.
This would allow all kinds of creative, cool and themely cybernetics to be designed and used but they would all be purely cosmetic. Those cool cyberlegs that look and work like ostrich legs don't make you faster or a better jumper but they do look cool. That windowed chrome dome that shows off your brain with black lights doesn't make you smarter but it looks cool.
I think that something like this would allow PCs to finally rock chrome on par with some well known bar tenders and owners and could (I hope) use a lot of existing code to make implementation a little easier maybe.
I could see fabricators either being available at various clinics or them being usable only at SK for a fee. I would also expect that, as with bio-mods, there would be some quality control steps and theme enforcement steps along the way - most of which could largely mirror what is already in place for bio-mods as a starting point.
