I still think a robot tail would be rather lame. No matter how much you soup it up with toxins and lasers and armour, it is still something that any character could get. Grimm prothetics are a unique opportunity for Salem's Faction and for them alone. They are an interesting twist on Grimm and the magic related to them. Heck, forget not knowing the capibilities of Grimm prosthetics in general, we don't know the capabilities of a Deathstalker. It could be venomous (and imagine how awesome Grimm venom would be) or have many other features, or those features could be added by Salem or Watts to make Tyrian's tail unique and more versitile than the Grimm it came from (like how Geists haven't shown the ability to have Stretch Armstrong arms or the ability to siphon power, but Cinder's Geist-like arm can).

Now, the one problem that you brought up that is incredibly detrimental to this idea is the fact taht Silver Eyes harm the Grimm so why would Salem Grimmify her henchman? Ultimately I can't really refute this point. It is a very logical argument. However, I will bring up 2 points in response to this to take into account.

1) Cinder already has a Grimm arm and no matter how you look at it, Salem is partially responsible for its creation. Why would Salem willingly send out her one Henchman (or henchwoman I guess) that is weak to Silver Eyes to go complete a mission where she'd likely come into contact with SIlver Eyes?

2) Merry don't have the best sense of logic in the world. Looking at the idiocy, plot holes, and retcons in the story so far, it is clear that Merry doesn't really follow the logic of their story when creating various details of the future story. I doubt they'd think of the logistics of Tyrian's tail, whther robotic or Grimm, and in fact they already haven't (as in how do you have an invertebrate tail attached to a vertebrate?)
