Just a random thought: Now that sheathes and holsters are implemented, it would be fun to have a Robocop-style implantable internal weapon storage. This could range from the semi-large thigh compartment that Robocop himself has to perhaps a small spring-loaded sheath or holster mounted inside the forearm that can carry a knife or hold-out type pistol.
The main counter-argument here would probably be “Why not just use a real sheath/holster?”. Well, obviously, they’re not as cool. Plus an implanted one could be used while otherwise naked, and wouldn’t cause bodily encumbrance. For a mechanical bonus, perhaps the cyber-holster-sheath could be tweaked such that you can always perform a perfect draw of your knife/quickdraw your gun/etc without requiring the prerequisite skill level. Concealment of weapons isn’t a big deal currently, but it would save you from having to deal with NPCs telling you to “drop the fucking $weapon, you monster!” whenever they see you. (If you play with them enabled, at least.)
If you want to boil it down to a realism argument, admittedly most of these concepts are designed for fully cybered robo-limbs without meat components and their accompanying biological constraints, which Cataclysm does not seem to have yet. But we already have Internal Torso Storage, so there’s clearly some body-safe storage technology in existence, and it doesn’t seem a huge leap to this idea.
I personally don’t imagine there’d be room anywhere in the body for an implantable scabbard; swords seem to be uniformly longer than a human thigh. I suppose while you could consider putting one straight down next to your spine, but you’d be unable to bend your torso at all if you also had a rigid blade weapon of some sort stuck in there…
