Yay, or Nay?
So, the items have a capacity greater than can fit inside a cyber-skull, but each has an essence cost as well.
My understanding is if an item has both, it uses either capacity, or essence.
That being the case, would it be possible to install the Junkyard Jaw and a Weapon Launcher combo (CF 91, CF 92), paying the full essence costs, to basically have a set of ballistic chompers?
Further down the rabbit hole:
Assuming the answer above is yes,
could taking the Voice Modulator (SR5 452) allow the character to still use vocal communication during the times that he's temporarily sans jaw-bone?
